CertMgr Class

Properties Methods Events Config Settings Errors

The CertMgr class is used to manage the digital certificates installed on a system.

Syntax

class inebank.CertMgr

Remarks

The class methods, such as list_certificate_stores or list_store_certificates, are used to list certificate stores and certificates. The corresponding lists are returned through the on_store_list and on_cert_list events. Encoded certificates are provided through the events.

You can load a certificate by setting the cert property of the class. Then you can get information about the certificate through the corresponding fields of the cert property (described below).

The cert_subject, cert_serial_number, and cert_issuer properties identify the certificate. The cert_effective_date and cert_expiration_date show the time boundaries of the certificate.

cert_public_key, cert_public_key_algorithm, cert_public_key_length, and cert_version provide information about the certificate keys and the certificate format (version).

cert_usage_flags specifies the intended usage of the certificate. The cert_usage property provides a text description of these flags.

The class supports both public and private keys in a variety of formats. When the cstAuto value is used the class will automatically determine the type. This property can take one of the following values:


0 (cstUser - default)	For Windows, this specifies that the certificate store is a certificate store owned by the current user. Note: this store type is not available in Java.
1 (cstMachine)	For Windows, this specifies that the certificate store is a machine store. Note: this store type is not available in Java.
2 (cstPFXFile)	The certificate store is the name of a PFX (PKCS12) file containing certificates.
3 (cstPFXBlob)	The certificate store is a string (binary or base64-encoded) representing a certificate store in PFX (PKCS12) format.
4 (cstJKSFile)	The certificate store is the name of a Java Key Store (JKS) file containing certificates. Note: this store type is only available in Java.
5 (cstJKSBlob)	The certificate store is a string (binary or base64-encoded) representing a certificate store in Java Key Store (JKS) format. Note: this store type is only available in Java.
6 (cstPEMKeyFile)	The certificate store is the name of a PEM-encoded file that contains a private key and an optional certificate.
7 (cstPEMKeyBlob)	The certificate store is a string (binary or base64-encoded) that contains a private key and an optional certificate.
8 (cstPublicKeyFile)	The certificate store is the name of a file that contains a PEM- or DER-encoded public key certificate.
9 (cstPublicKeyBlob)	The certificate store is a string (binary or base64-encoded) that contains a PEM- or DER-encoded public key certificate.
10 (cstSSHPublicKeyBlob)	The certificate store is a string (binary or base64-encoded) that contains an SSH-style public key.
11 (cstP7BFile)	The certificate store is the name of a PKCS7 file containing certificates.
12 (cstP7BBlob)	The certificate store is a string (binary) representing a certificate store in PKCS7 format.
13 (cstSSHPublicKeyFile)	The certificate store is the name of a file that contains an SSH-style public key.
14 (cstPPKFile)	The certificate store is the name of a file that contains a PPK (PuTTY Private Key).
15 (cstPPKBlob)	The certificate store is a string (binary) that contains a PPK (PuTTY Private Key).
16 (cstXMLFile)	The certificate store is the name of a file that contains a certificate in XML format.
17 (cstXMLBlob)	The certificate store is a string that contains a certificate in XML format.
18 (cstJWKFile)	The certificate store is the name of a file that contains a JWK (JSON Web Key).
19 (cstJWKBlob)	The certificate store is a string that contains a JWK (JSON Web Key).
21 (cstBCFKSFile)	The certificate store is the name of a file that contains a BCFKS (Bouncy Castle FIPS Key Store). Note: this store type is only available in Java and .NET.
22 (cstBCFKSBlob)	The certificate store is a string (binary or base64-encoded) representing a certificate store in BCFKS (Bouncy Castle FIPS Key Store) format. Note: this store type is only available in Java and .NET.
23 (cstPKCS11)	The certificate is present on a physical security key accessible via a PKCS11 interface. To use a security key the necessary data must first be collected using the CertMgr class. The list_store_certificates method may be called after setting cert_store_type to `cstPKCS11`, cert_store_password to the PIN, and cert_store to the full path of the PKCS11 dll. The certificate information returned in the on_cert_list event's `CertEncoded` parameter may be saved for later use. When using a certificate, pass the previously saved security key information as the and set to the PIN. Code Example: SSH Authentication with Security Key `certmgr.CertStoreType = CertStoreTypes.cstPKCS11; certmgr.OnCertList += (s, e) => { secKeyBlob = e.CertEncoded; }; certmgr.CertStore = @"C:\Program Files\OpenSC Project\OpenSC\pkcs11\opensc-pkcs11.dll"; certmgr.CertStorePassword = "123456"; //PIN certmgr.ListStoreCertificates(); sftp.SSHCert = new Certificate(CertStoreTypes.cstPKCS11, secKeyBlob, "123456", "*"); sftp.SSHUser = "test"; sftp.SSHLogon("myhost", 22);`
99 (cstAuto)	The store type is automatically detected from the input data. This setting may be used with both public and private keys and can detect any of the supported formats automatically.

exported_cert Property

This is the exported certificate string.

Syntax

def get_exported_cert() -> bytes: ...

exported_cert = property(get_exported_cert, None)

Default Value

Remarks

This property holds the exported certificate if it was not exported to a file.

When calling export_certificate if the CertFile parameter is an empty string, the certificate will be exported as a string and available in this property. This allows certificate data to be exported without writing any data to disk.

When export_format is set to PFX or P7B, the EncodeExportedCert setting controls whether the value is binary or Base64 encoded.

This property is read-only.

export_format Property

This is the format to which the certificate is exported.

Syntax

def get_export_format() -> str: ...
def set_export_format(value: str) -> None: ...

export_format = property(get_export_format, set_export_format)

Default Value

"PFX"

Remarks

export_format is applicable when export_certificate is called and may be used to specify the output format. The applicability of each format depends on whether export_private_key is set. Some formats are applicable only when exporting to a private key and some values are applicable only when exporting to a public key.


ExportFormat	Applicability	Description

"PEM"	Public and Private Keys	A PEM-formatted public certificate (X509/PKCS1/PKCS8), or PEM formatted private key (PKCS1/PKCS8). When export_private_key is False the exported certificate will be a PEM formatted X509 public certificate if the certificate being exported includes X509 data. If no X509 information is present, the public key will be exported in PKCS1 public key format for RSA/DSA keys and PKCS8 public key format for ECDSA/EdDSA keys. When export_private_key is True the exported certificate will be a PEM-formatted PKCS1 private key for RSA/DSA keys and a PEM-formatted PKCS8 private key for ECDSA/EdDSA keys.

export_private_key Property

This controls whether to export the private key.

Syntax

def get_export_private_key() -> bool: ...
def set_export_private_key(value: bool) -> None: ...

export_private_key = property(get_export_private_key, set_export_private_key)

Default Value

TRUE

Remarks

This property controls whether the private key is exported when export_certificate is called.

If set to True (default), the private key is exported. If set to False, only the public key is exported.

config Method

Sets or retrieves a configuration setting.

Syntax

def config(configuration_string: str) -> str: ...

Remarks

config is a generic method available in every class. It is used to set and retrieve configuration settings for the class.

These settings are similar in functionality to properties, but they are rarely used. In order to avoid "polluting" the property namespace of the class, access to these internal properties is provided through the config method.

To set a configuration setting named PROPERTY, you must call Config("PROPERTY=VALUE"), where VALUE is the value of the setting expressed as a string. For boolean values, use the strings "True", "False", "0", "1", "Yes", or "No" (case does not matter).

To read (query) the value of a configuration setting, you must call Config("PROPERTY"). The value will be returned as a string.

create_certificate Method

This method creates a new self-signed certificate in the current store.

Syntax

def create_certificate(cert_subject: str, serial_number: int) -> None: ...

Remarks

This method creates a new self-signed certificate in the current store, which contains the following:

CertSubject specifies the subject of the new certificate. A new keyset (public/private key pair) is generated and associated with the new certificate.


Field	Meaning
CN	Common Name. This is commonly a host name like www.server.com.
O	Organization
OU	Organizational Unit
L	Locality
S	State
C	Country
E	Email Address

If a field value contains a comma it must be quoted.

SerialNumber specifies the certificate serial number. All certificates signed by the same issuer must have different (unique) serial numbers.

The time validity of the new certificate is determined by the CertValidityTime configuration setting, and the key size by the CertKeyLength configuration setting.

In the Unix edition of the toolkit, the certificate will be created in memory. Call export_certificate to export the newly created certificate to a PEM file.

create_key Method

This method creates a new keyset associated with the provided name.

Syntax

def create_key(key_name: str) -> None: ...

Remarks

This method will create a new keyset (public/private key pair) within the Cryptographic Service Provider (CSP) used by the class. The CSP can be set using the CSP configuration setting.

NOTE: This functionality is only available in Windows.

delete_certificate Method

This method deletes the currently selected certificate from the store.

Syntax

def delete_certificate() -> None: ...

Remarks

This method will delete the selected certificate from the store. If the certificate cannot be deleted, an error is returned.

This functionality is currently not available when the provider is OpenSSL.

delete_key Method

This method deletes the keyset associated with the provided name.

Syntax

def delete_key(key_name: str) -> None: ...

Remarks

This method will delete the keyset (public/private key pair) associated with KeyName from the Cryptographic Service Provider (CSP). The CSP can be set using the CSP configuration setting.

NOTE: This functionality is only available in Windows.

export_certificate Method

This method exports the currently selected certificate.

Syntax

def export_certificate(cert_file: str, password: str) -> None: ...

Remarks

This method exports the certificate currently selected by cert_subject to the file specified by the CertFile parameter in the format specified by export_format. This method may be used effectively to convert between a variety of formats.

The Password parameter specifies a password for the private key when export_private_key is set to True. Password is not applicable when export_private_key is set to False.

If CertFile is set to an empty string, the exported certificate will not be written to disk and instead will be held as a string by the exported_cert property.

import_certificate Method

This method imports a certificate from a file into the current certificate store.

Syntax

def import_certificate(cert_file: str, password: str, subject: str) -> None: ...

Remarks

This method will import a certificate from a file into the current certificate store.

On Windows platforms, certificates may be imported only to the Windows certificate store. To load a certificate without importing it to a Windows store, set Cert*.

Certificate files with or without a private key may be imported. If the file specified by CertFile contains a private key, the private key will be imported along with the public certificate. If the file specified by CertFile contains only a public certificate, only the public certificate will be imported.

The Password parameter specifies the certificate password (if any). When importing a public certificate, set Password to an empty string.

The format of the certificate file being imported must contain valid X509 data to be imported. Not all certificate file formats include X509 data, such as PPK or PKCS8 private keys. If the CertFile is of a format that cannot be imported, the class fails with an error.

Note: On Linux-based operating systems, this method loads the specified certificate without importing into any system location.

Subject is optional. If empty, the first certificate in the store is loaded instead of the matching certificate.

ImportCertificate Example

//Import a PFX certmgr.ImportCertificate("..\\test.pfx", "password", "*"); //Import a public certificate (CER) certmgr.ImportCertificate("..\\test.cer", "", "*");

import_signed_csr Method

This method mports a signed Certificate Signing Request (CSR).

Syntax

def import_signed_csr(signed_csr: bytes, key_name: str) -> None: ...

Remarks

This method will import a signed CSR. SignedCSR specifies a certificate that has been signed by a trusted authority. KeyName is the name of the keyset (public/private key pair) that was used to create the original CSR.

NOTE: This functionality is only available in Windows.

issue_certificate Method

This creates a new certificate in the current store and is signed by the selected certificate.

Syntax

def issue_certificate(cert_subject: str, serial_number: int) -> None: ...

Remarks

This method creates a new certificate in the current store and is signed by the selected certificate. CertSubject specifies the subject of the new certificate. A new keyset (public/private key pair) is generated and associated with the new certificate.


Field	Meaning
CN	Common Name. This is commonly a host name like www.server.com.
O	Organization
OU	Organizational Unit
L	Locality
S	State
C	Country
E	Email Address

If a field value contains a comma it must be quoted.

SerialNumber specifies the certificate serial number. All certificates signed by the same issuer must have different (unique) serial numbers.

The current certificate selected by the class will be used as the issuing certificate.

If no certificate has been selected in the current cert_store before calling this method, or if the selected certificate does not have an associated private key, the method fails with an error.

The time validity of the new certificate is determined by the CertValidityTime configuration setting, and the key size by the CertKeyLength configuration setting.

NOTE: This functionality is only available in Windows.

list_certificate_stores Method

This lists the certificate stores.

Syntax

def list_certificate_stores() -> str: ...

Remarks

This method lists the system certificate stores for the current user account. The results are provided through the on_store_list event.

The same information is also returned upon method completion as a set of lines and is given one per certificate store name.

NOTE: This functionality is only available in Windows.

list_keys Method

This lists the keysets in a Cryptographic Service Provider (CSP).

Syntax

def list_keys() -> str: ...

Remarks

This method lists the keys (public/private key pairs) in a CSP. The results are provided through the on_key_list event.

The same information is also returned upon method completion as a set of lines and is given one per key, with each line containing the following information separated by Tab characters: KeyContainer, KeyType, AlgId, and KeyLen.

NOTE: This functionality is only available in Windows.

list_machine_stores Method

This lists the machine certificate stores.

Syntax

def list_machine_stores() -> str: ...

Remarks

This method behaves the same as the list_certificate_stores method, but it lists the certificate stores in the machine account (under HKEY_LOCAL_MACHINE in the registry).

NOTE: This functionality is only available in Windows.

list_store_certificates Method

This lists the certificates in a store.

Syntax

def list_store_certificates() -> str: ...

Remarks

This method lists the certificates in a store. The results are provided through the on_cert_list event.

The same information is also returned upon method completion as a set of lines and is given one per certificate, with each line containing the following information separated by Tab characters: CertSubject, CertIssuer, CertSerialNumber, and HasPrivateKey (as "1" or "0").

In the Unix edition of the toolkit, this is available only when a PFX file is loaded.

read_certificate Method

This loads a certificate from a file.

Syntax

def read_certificate(file_name: str) -> None: ...

Remarks

Note: This method is present for backward compatibility. It is recommended to specify the Cert* properties to load a certificate.

reset Method

This resets all certificate properties to their default values.

Syntax

def reset() -> None: ...

Remarks

This method will reset all certificate properties to their default values. If a certificate and a private key are selected or a certificate store is opened, both are released upon calling this method.

save_certificate Method

This method saves the currently selected public certificate to a file.

Syntax

def save_certificate(file_name: str) -> None: ...

Remarks

Note: This method is present for backward compatibility. It is recommended to use export_certificate to export both public and private certificates and keys.

This method saves the public certificate of the currently selected certificate in Base64 PEM format to the location specified by the FileName parameter.

If the destination file exists, it is overwritten.

show_certificate_chain Method

This shows the certificate chain.

Syntax

def show_certificate_chain() -> str: ...

Remarks

This method shows the certificate chain for the certificate. The results are provided through the on_cert_chain event.

NOTE: This functionality is only available in Windows.

sign_csr Method

This creates a signed certificate from a Certificate Signing Request (CSR).

Syntax

def sign_csr(csr: bytes, serial_number: int) -> str: ...

Remarks

This method will create a signed certificate from a CSR. CSR specifies the CSR to be signed.

SerialNumber specifies the certificate serial number. All certificates signed by the same issuer must have different (unique) serial numbers.

The time validity of the new certificate is determined by the CertValidityTime configuration setting, and the key size is determined by the CertKeyLength configuration setting.

NOTE: This functionality is only available in Windows.

The on_cert_list event and the list_store_certificates method are used to list the certificates in the store.

CertMgr Config Settings

The class accepts one or more of the following configuration settings. Configuration settings are similar in functionality to properties, but they are rarely used. In order to avoid "polluting" the property namespace of the class, access to these internal properties is provided through the config method.

CertMgr Config Settings

CertComment: A comment to include in a saved certificate.

This settings specifies the certificate comment when calling export_certificate. This setting is applicable only when export_format is set to one of the following values:

OpenSSHKey (export_private_key must be False)
SSH2PublicKey
PPK

When export_format is set to SSH2PublicKey, the value of this setting must be the full header (e.g., Comment: My Comment).

CertCustomExtensionCount: The number of records in the CertCustomExtension arrays.

This property controls the size of the following arrays:

CertCustomExtensionCritical[i];
CertCustomExtensionOID[i];
CertCustomExtensionValue[i];

The array indices start at 0 and end at CertExtensionCount-1.

CertCustomExtensionCritical[i]: Whether or not the extension is defined as critical.

Whether or not the certificate extension at index "i" is defined as critical.

Valid array indices are from 0 to CertCustomExtensionCount - 1.

CertCustomExtensionOID[i]: The ASN of the extension at index 'i'.

The ASN.1 object identifier (OID) that defines the certificate extension at index 'i'.

Valid array indices are from 0 to CertCustomExtensionCount - 1.

CertCustomExtensionValue[i]: The raw value of the extension at index 'i'.

The raw value of this certificate extension (as a byte string). This value is encoded according to the extension's ASN.1 specification.

Valid array indices are from 0 to CertCustomExtensionCount - 1.

CertExtendedKeyUsage: The extended key usage of the certificate.

This setting specifies the extended key usage flags of the certificate created by calling create_certificate or issue_certificate. If specified, the value is a comma-separated list of OIDs. Common OIDs are as follows:


1.3.6.1.5.5.7.3.1	Server Authentication
1.3.6.1.5.5.7.3.2	Client Authentication
1.3.6.1.5.5.7.3.3	Code Signing
1.3.6.1.5.5.7.3.4	Secure Email
1.3.6.1.5.5.7.3.8	Time Stamping
1.3.6.1.5.5.7.3.9	OCSP Signing

For instance, the following value specified the extended key usage for Server Authentication, Client Authentication, and Code Signing: 1.3.6.1.5.5.7.3.1, 1.3.6.1.5.5.7.3.2, and 1.3.6.1.5.5.7.3.3

CertKeyLength: The public key length for created certificates and keys.

When create_certificate creates a new certificate and associated key, or when create_key creates a key, this setting determines the length of the new public key (in bits). The default value is 2048.

CertKeyType: The types of keys created for new certificates.

When create_certificate creates a new certificate and associated key, or when create_key creates a key, this setting determines the type of key generated: 1 for key exchange (encryption) keys, and 2 for digital signature keys. The default value is 1.

CertPublicKeyAlgorithm: The public key algorithm used when a certificate is created.

When create_certificate creates a new certificate and associated key, this setting determines the public key algorithm of the generated keys. Following are the valid values:

RSA (default)
DSA
ECDSA_P256
ECDSA_P384
ECDSA_P521
ECDSA_Secp256k1

MD2
MD5
SHA1
SHA256 (default)
SHA384
SHA512

CertSubjectAltNames: Subject Alternative Names for creating or issuing certificates.

This allows the Subject Alternative Names extension to be specified when creating or issuing a certificate via create_certificate or issue_certificate. This setting only supports email, DNS, URI, and IPv4 addresses. Separate alternative names should be separated by commas. For example:

string altNames = "email:copy,dns:domain.com,dns.1:other.domain.com,uri:http://www.domain.com,ip:192.168.1.102"

CertUsageFlags: Sets the flags indicating the usage of the created certificate.

This setting specifies the usage flags of the certificate created by calling create_certificate or issue_certificate. If specified, the value is the binary or one or more of the supported values. For instance a value of 12 or 0xC is the binary or is one of the Certificate Signing and Key Signing usage flags. Following are the supported flags:


0x80	Digital Signatures
0x40	Key Authentication
0x20	Key Encryption
0x10	Data Encryption
0x08	Key Agreement
0x04	Certificate Signing
0x02	Key Signing

CertValidityOffset: The number of days until the certificate becomes valid.

This configuration setting can be used to change when a newly created certificate becomes valid. By default, the certificate is valid as soon as it is created. Set CertValidityOffset to the number of days that this starting period should be offset from the current day. This setting also accepts negative values for back-dating the validity of a certificate. The default value is 0.

CertValidityTime: The validity period for the certificate.

This configuration setting determines the duration in days that a newly created certificate remains valid. The certificate becomes valid as soon as it is created, unless CertValidityOffset is set. The duration is not changed if CertValidityOffset is set; the certificate will still expire CertValidityTime days after the validity period begins. The default value is 365 days.

CheckCRL: Checks the Certificate Revocation List for the selected certificate.

When queried, this setting will check the Certificate Revocation List specified by the currently loaded cert. The class will first obtain the list of CRL URLs from the certificate's CRL distribution points extension. The class will then make HTTP requests to each CRL endpoint to check the validity of the certificate. If the certificate has been revoked or any other issues are found during validation the class fails with an error.

This configuration setting is only supported in the Java, C#, and C++ editions. In the C++ edition, it is only supported on Windows operating systems.

CheckOCSP: Uses OCSP to check the status of the selected certificate.

When queried, the class will use OCSP to check the validity of the currently loaded cert. The class will first obtain the OCSP URL from the certificate's OCSP extension. The class will then locate the issuing certificate and make an HTTP request to the OCSP endpoint to check the validity of the certificate. If the certificate has been revoked or any other issues are found during validation the class fails with an error.

This configuration setting is only supported in the Java, C#, and C++ editions. In the C++ edition, it is only supported on Windows operating systems.

CreatedKey: The PKCS8 formatted private and public key pair created after calling CreateKey.

This setting returns the PKCS8 formatted private and public key pair of the key created when create_key is called. This is useful in scenarios where exporting the key for use in another environment is required.

CSP: The Cryptographic Service Provider.

The name of the Cryptographic Service Provider used to provide access to certificate signing operations.

CSRIgnoredExtensions: Extensions to be ignorned when signing a CSR.

Set this configuration setting to a comma separated list of OID's of any extensions already present in the CSR that should be ignored when the CSR is signed.

For example if the SAN's in a CSR should be ignored the below code would work: CertMgr1->Config("CSRIgnoredExtensions=2.5.29.17");

CSRKey: The PKCS8 formatted private key to use when generating a CSR.

This setting optionally specifies a PKCS8 formatted private key to use when calling generate_csr. When set, the keyName parameter of generate_csr is ignored and the key specified by this setting is used instead.

EncodeExportedCert: Whether the certificate being exported to a string is encoded.

This setting controls whether the certificate exported as a string when export_certificate is called is encoded. If export_format is set to PFX or P7B before calling export_certificate the exported certificate may be binary (EncodeExportedCert is False), or base64 encoded (EncodeExportedCert is True) to allow easier handling of the certificate data.

The default value is False.

HasCRL: Whether the certificate supports the CRL extension.

This setting returns true if the currently loaded cert supports the CRL extension.

This configuration setting is only supported in the Java, C#, and C++ editions. In the C++ edition, it is only supported on Windows operating systems.

HasOCSP: Whether the certificate supports the OCSP extension.

This setting returns true if the currently loaded cert supports the OCSP extension.

This configuration setting is only supported in the Java, C#, and C++ editions. In the C++ edition, it is only supported on Windows operating systems.

ImportCertAction: Specified the action to take if a matching certificate or a link to a matching certificate already exists.

When calling import_certificate if a matching certificate or a link to a matching certificate already exists in the Windows certificate store this setting governs what action will be taken. Possible values are:


1	CERT_STORE_ADD_NEW - Imports a certificate only if no existing certificate is present.
2	CERT_STORE_ADD_USE_EXISTING - If an existing certificate is found, it is not replaced.
3 (default)	CERT_STORE_ADD_REPLACE_EXISTING - If an existing certificate is found it is replaced.
4	CERT_STORE_ADD_ALWAYS - No checks are performed and a new certificate is always added to the store. This can result in duplicates.
5	CERT_STORE_ADD_REPLACE_EXISTING_INHERIT_PROPERTIES - If an existing certificate is found it is replaced, and the new certificate inherits properties from the certificate it replaces.
6	CERT_STORE_ADD_NEWER - Imports a certificate only if the certificate is newer than an existing matching certificate.
7	CERT_STORE_ADD_NEWER_INHERIT_PROPERTIES - Imports a certificate only if the certificate is newer than an existing matching certificate, and inherits the properties of old certificate it replaces.

ImportCertStoreType: The type of certificate store being specified for import.

When calling import_certificate, this setting controls the type of the certificate being specified in the first parameter.

This config can take one of the following values:


2 (cstPFXFile)	The certificate store is the name of a PFX (PKCS12) file containing certificates.
3 (cstPFXBlob)	The certificate store is a string (binary or base64-encoded) representing a certificate store in PFX (PKCS12) format.
6 (cstPEMKeyFile)	The certificate store is the name of a PEM-encoded file that contains a private key and an optional certificate.
7 (cstPEMKeyBlob)	The certificate store is a string (binary or base64-encoded) that contains a private key and an optional certificate.
8 (cstPublicKeyFile)	The certificate store is the name of a file that contains a PEM- or DER-encoded public key certificate.
9 (cstPublicKeyBlob)	The certificate store is a string (binary or base64-encoded) that contains a PEM- or DER-encoded public key certificate.
10 (cstSSHPublicKeyBlob)	The certificate store is a string (binary or base64-encoded) that contains an SSH-style public key.
13 (cstSSHPublicKeyFile)	The certificate store is the name of a file that contains an SSH-style public key.
99 (cstAuto - default)	The certificate type is automatically determined from the input.

Note that this functionality is currently for Windows platforms only.

JWKAlgorithm: The JWK algorithm.

This setting specifies the JWK algorithm. It can be set before calling export_certificate (if export_format is set to JWK) to control the key algorithm used to create the JWK. This setting will also be populated after loading a JWK file.

Valid values are:

(empty string)
HS256
HS384
HS512
RS256
RS384
RS512
EC256
EC384
EC512
EC256K

JWKExportX5C: Whether to export a certificate chain to the x5c parameter.

When set to true, the component will attempt to build the X.509 certificate chain for the certificate currently selected by cert_subject. If successful, the x5c parameter will be added to the JWK. It can be set before calling export_certificate (if export_format is set to JWK).

The default value is False.

JWKKeyId: The JWK key Id.

This setting specifies the JWK key Id. It can be set before calling export_certificate (if export_format is set to JWK). This setting will also be populated after loading a JWK file.

JWKKeyOps: The JWK intended key operations list.

This setting specifies the intended key operations for the JWK. It can be set before calling export_certificate (if export_format is set to JWK). This setting will also be populated after loading a JWK file.

This setting format is a JSON array. Examples: ["sign","verify"] or ["encrypt"].

JWKUse: The JWK use parameter value.

This setting specifies the intended usage of the key. It can be set before calling export_certificate (if export_format is set to JWK). This setting will also be populated after loading a JWK file.

Valid values are enc and sig.

KeyFormat: How the public and private key are formatted.

This setting controls the format of cert_public_key and cert_private_key. By default these properties hold PEM formatted public and private key data. When set to 1 (XML) the keys are stored in a XML format. This only affects the values returned by the class; the actual keys remain the same regardless of this setting. Possible values are:

0 (PEM - default)
1 (XML)

The default value is 0 (PEM).

LogLevel: The level of detail that is logged.

This setting controls the level of detail that is logged through the on_log event. Possible values are:


0 (None)	No events are logged.
1 (Info - default)	Informational events are logged.
2 (Verbose)	Detailed data are logged.
3 (Debug)	Debug data are logged.

ReplaceKey: Whether or not to replace an existing key when creating a new key.

If this is false (default), the component will throw an error if a duplicate key exists while generating a new keyset using create_key. If set to true, the component will replace a key if it already exists when generating new keys.

RequestSubjectAltNames: Subject Alternative Names for a Certificate Signing Request.

This allows Subject Alternative Names to be added to a Certificate Signing request. The setting only supports email, DNS, URI, and IPv4 addresses. Separate alternative names should be separated by commas. For example:

string altNames = "email:copy,dns:domain.com,dns.1:other.domain.com,uri:http://www.domain.com,ip:192.168.1.102"

X509Algorithm: Public Key Algorithm OID.

This setting exposes the Public Key Algorithm object identifier (OID) value for the currently loaded cert.

LicenseInfo: Information about the current license.

When queried, this setting will return a string containing information about the license this instance of a class is using. It will return the following information:

Product: The product the license is for.
Product Key: The key the license was generated from.
License Source: Where the license was found (e.g., RuntimeLicense, License File).
License Type: The type of license installed (e.g., Royalty Free, Single Server).
Last Valid Build: The last valid build number for which the license will work.

MaskSensitive: Whether sensitive data is masked in log messages.

In certain circumstances it may be beneficial to mask sensitive data, like passwords, in log messages. Set this to True to mask sensitive data. The default is True.

This setting only works on these classes: AS3Receiver, AS3Sender, Atom, Client(3DS), FTP, FTPServer, IMAP, OFTPClient, SSHClient, SCP, Server(3DS), Sexec, SFTP, SFTPServer, SSHServer, TCPClient, TCPServer.

ProcessIdleEvents: Whether the class uses its internal event loop to process events when the main thread is idle.

If set to False, the class will not fire internal idle events. Set this to False to use the class in a background thread on Mac OS. By default, this setting is True.

SelectWaitMillis: The length of time in milliseconds the class will wait when DoEvents is called if there are no events to process.

If there are no events to process when do_events is called, the class will wait for the amount of time specified here before returning. The default value is 20.

UseInternalSecurityAPI: Tells the class whether or not to use the system security libraries or an internal implementation.

When set to False, the class will use the system security libraries by default to perform cryptographic functions where applicable.

Setting this setting to True tells the class to use the internal implementation instead of using the system security libraries.

On Windows, this setting is set to False by default. On Linux/macOS, this setting is set to True by default.

To use the system security libraries for Linux, OpenSSL support must be enabled. For more information on how to enable OpenSSL, please refer to the OpenSSL Notes section.
