The FDMSRegister component is a tool used to Register and Activate a merchant account with the Datawire VXN. This allows you to send transactions through the Datawire system to the First Data Merchant Services (FDMS) processor. This component is also used to find the appropriate URLs to which authorizations and settlements will be posted.

Syntax

DPayments.DPaymentsSDK.Fdmsregister

Remarks

The FDMSRegister component is a tool used to Register and Activate a merchant account with the Datawire VXN. This component communicates with the Datawire VXN transaction transport network, and allows you to set up your account so that credit card transactions made with the FDMSECommerce, FDMSRetail, and FDMSSettle components will pass through Datawire and ultimately reach the First Data Merchant Services (FDMS) transaction processor. Before you can charge a single credit card, you must Register and Activate your FDMS account, and then run a ServiceDiscovery to find acceptable URLs, which you will ultimately use to send credit card authorizations.

The first thing you must do is Register your merchant account. First Data Merchant Services will provide you with a MerchantNumber and a MerchantTerminalNumber, which are required for registering with Datawire. If you are registering on the Rapid Connect platform you must also set the GroupId configuration setting. In addition, you will need to set the TransactionNumber with a unique value (the TransactionNumber should be incremented for each transaction you send to the Datawire VXN). The example below also sets the URL to point to the Datawire test server.

FDMSRegister.MerchantNumber = "000000999990"; FDMSRegister.MerchantTerminalNumber = "555555"; //FDMSRegister.Config("GroupId=FDMS_Assigned_GroupId"); //Rapid Connect Only FDMSRegister.TransactionNumber = "0000001V002500" 'any unique number will do; check TransactionNumber property for format FDMSRegister.URL = "https://stagingsupport.datawire.net/staging_expresso/SRS.do" FDMSRegister.Register()

If the registration was successful, the DatawireStatus will contain "OK", and the DatawireId will contain the new Id which you must save and send with every subsequent transaction. The PrimaryDiscoveryURL and SecondaryDiscoveryURL properties will also be filled after a successful authorization. These URLs should be saved for later, and used to perform ServiceDiscovery.

After registering, you must immediately Activate the merchant. If you wait too long, your registration will time out, and you will have to contact Datawire to have them reset your account so that you may register again. When activating the merchant, the same properties are required as for the Register method, with the addition of the DatawireId property. Since the call to Register filled the DatawireId property with the correct value, all we need to do now is:

FDMSRegister.TransactionNumber = "0000002V002500" 'any unique number will do; check TransactionNumber property for format FDMSRegister.Activate()

After registering and activating the account, you may now move on to Service Discovery. The Register method will return both a PrimaryDiscoveryURL and a SecondaryDiscoveryURL. Use these URLs with the ServiceDiscovery method to retrieve a list of valid transaction URLs. For instance:

FDMSRegister.ServiceDiscovery("https://staging1.datawire.net/sd")

After a successful ServiceDiscovery the DatawireStatus will be "OK". The discovered URLs will be listed in the ServiceProviders array property. At this time, you should Ping each of these URLs and sort them in order of fastest to slowest response time. You will use the URL with the fastest response time to authorize transactions with FDMSRetail or FDMSECommerce. If the first URL stops responding, you should remove the URL and switch to the next URL in the list. The following example shows how to ping each of the ServiceProviders (you must save and sort the results yourself).

for (int i = 0; i < FDMSRegister.ServiceProviders.Length; i++) { FDMSRegister.Ping(FDMSRegister.ServiceProviders[i]); Console.WriteLine(FDMSRegister.ServiceProviders[i] + " = " + FDMSRegister.PingResponseTime); }

If your list of servers becomes empty, perform ServiceDiscovery and the subsequent steps to re-populate the list of available servers.

You may now use the DatawireId and the Service Provider URLs retrieved by this component to submit transactions using the FDMSECommerce, FDMSRetail, and FDMSSettle components.

This property is read-only.

SSLAcceptServerCert Property (FDMSRegister Component)

Instructs the component to unconditionally accept the server certificate that matches the supplied certificate.

Syntax

• C#
• VB.NET

public Certificate SSLAcceptServerCert { get; set; }

Public Property SSLAcceptServerCert As Certificate

Remarks

If it finds any issues with the certificate presented by the server, the component will normally terminate the connection with an error.

You may override this behavior by supplying a value for SSLAcceptServerCert. If the certificate supplied in SSLAcceptServerCert is the same as the certificate presented by the server, then the server certificate is accepted unconditionally, and the connection will continue normally.

Please note that this functionality is provided only for cases where you otherwise know that you are communicating with the right server. If used improperly, this property may create a security breach. Use it at your own risk.

SSLCert Property (FDMSRegister Component)

The certificate to be used during SSL negotiation.

Syntax

• C#
• VB.NET

public Certificate SSLCert { get; set; }

Public Property SSLCert As Certificate

Remarks

The digital certificate that the component will use during SSL negotiation. Set this property to a valid certificate before starting SSL negotiation. To set a certificate, you may set the Encoded field to the encoded certificate. To select a certificate, use the store and subject fields.

SSLProvider Property (FDMSRegister Component)

This specifies the SSL/TLS implementation to use.

Syntax

• C#
• VB.NET

public FdmsregisterSSLProviders SSLProvider { get; set; }

enum FdmsregisterSSLProviders {
  sslpAutomatic,
  sslpPlatform,
  sslpInternal
}

Public Property SSLProvider As FdmsregisterSSLProviders

Enum FdmsregisterSSLProviders
  sslpAutomatic
  sslpPlatform
  sslpInternal
End Enum

Default Value

0

Remarks

This property specifies the SSL/TLS implementation to use. In most cases the default value of 0 (Automatic) is recommended and should not be changed. When set to 0 (Automatic) the component will select whether to use the platform implementation or the internal implementation depending on the operating system as well as the TLS version being used.

Possible values are:

In most cases using the default value (Automatic) is recommended. The component will select a provider depending on the current platform.

When Automatic is selected, on Windows the component will use the platform implementation. On Linux/macOS the component will use the internal implementation. When TLS 1.3 is enabled via SSLEnabledProtocols the internal implementation is used on all platforms.

The .NET Standard library will always use the internal implementation on all platforms.

SSLServerCert Property (FDMSRegister Component)

The server certificate for the last established connection.

Syntax

• C#
• VB.NET

public Certificate SSLServerCert { get; }

Public ReadOnly Property SSLServerCert As Certificate

Remarks

SSLServerCert contains the server certificate for the last established connection.

SSLServerCert is reset every time a new connection is attempted.

This property is read-only.

Timeout Property (FDMSRegister Component)

A timeout for the component.

Syntax

• C#
• VB.NET

public int Timeout { get; set; }

Public Property Timeout As Integer

Default Value

30

Remarks

If Timeout is set to a positive value, and an operation cannot be completed immediately, the component will return with an error after Timeout seconds.

The default value for Timeout is 30 (seconds).

TransactionNumber Property (FDMSRegister Component)

Uniquely identifies the transaction.

Syntax

• C#
• VB.NET

public string TransactionNumber { get; set; }

Public Property TransactionNumber As String

Default Value

""

Remarks

The TransactionNumber (otherwise known as the Client Reference Number, or ClientRef) uniquely identifies the packet sent by the application to the Datawire system. This parameter stores some unique token of information, and is used to match the response to the initial request sent. For example, the client application could use a static counter that is increased with the each executed request.

For all components except FDMSGiftCard the maximum length of this property is 14 alphanumeric characters.

The FDMS recommended format is "tttttttVnnnnrrr" where ttttttt is a 7 digit transaction id, V is a constant, and nnn is a 3 digit version number and rrr is a 3 digit revision number. The 6 digit version number is typically static but unique for an application (Example: Version 2.5 = tttttttV002500).

For the Rapid Connect platform, the 6 character version number should be your Project/TPPID value. The entire TransactionNumber must be unique within a 24 hour time period.

The FDMSGiftCard also passes this value to the FDMS Closed Loop Gift Card system as a transaction id, and therefore the following restrictions are enforced: The maximum length is 7 characters. If the first character is an 'X', the remaining characters must be in the range '0' through 'F', indicating a hexadecimal number. Otherwise the FDMS Closed Loop Gift Card system only allows digits in this property.

URL Property (FDMSRegister Component)

Location of the Datawire server to which transactions are sent.

Syntax

• C#
• VB.NET

public string URL { get; set; }

Public Property URL As String

Default Value

"https://support.datawire.net/production_expresso/SRS.do"

Remarks

This URL is used by the Register and Activate methods to provision the merchant. The following URLs are available for use:

For the Rapid Connect platform, URL will be populated after a successful ServiceDiscovery request.

Activate Method (FDMSRegister Component)

Activates a merchant account on the Datawire VXN.

Syntax

• C#
• VB.NET

public void Activate();

Public Sub Activate()

Remarks

After you have successfully registered, you will still not be able to send transactions using the Datawire VXN until you activate your account. For the security reasons, a merchant is required to activate within a limited time period after receiving a successful registration response. Otherwise, the Datawire VXN will deactivate the account and you will need to restart the registration process again.

North, Nashville, and Omaha:

For example:

FDMSRegister.MerchantNumber = "000000999990"; FDMSRegister.MerchantTerminalNumber = "555555"; FDMSRegister.TransactionNumber = "0000001V002500"; //any unique number will do; check TransactionNumber property for format FDMSRegister.URL = "https://stagingsupport.datawire.net/staging_expresso/SRS.do"; FDMSRegister.Register(); FDMSRegister.TransactionNumber = "0000002V002500"; //any unique number will do; check TransactionNumber property for format FDMSRegister.Activate(); FDMSRegister.ServiceDiscovery(FDMSRegister.PrimaryDiscoveryURL); for (int i = 0; i < FDMSRegister.ServiceProviders.Length; i++) { FDMSRegister.Ping(FDMSRegister.ServiceProviders[i]); Console.WriteLine(FDMSRegister.ServiceProviders[i] + " = " + FDMSRegister.PingResponseTime); }

Rapid Connect:

For example:

FDMSRegister.MerchantNumber = "000000999990"; FDMSRegister.MerchantTerminalNumber = "555555"; FDMSRegister.Config("GroupId=10001"); FDMSRegister.TransactionNumber = "0000001VRC1234"; //any unique number will do; check TransactionNumber property for format FDMSRegister.ServiceDiscovery("https://prod.dw.us.fdcnet.biz/sd/srsxml.rc"); FDMSRegister.ApplicationId = "RAPIDCONNECTSRS"; FDMSRegister.TransactionNumber = "0000002VRC1234" //any unique number will do; check TransactionNumber property for format FDMSRegister.Register(); FDMSRegister.TransactionNumber = "0000003VRC1234" //any unique number will do; check TransactionNumber property for format FDMSRegister.Activate();

Config Method (FDMSRegister Component)

Sets or retrieves a configuration setting.

Syntax

• C#
• VB.NET

public string Config(string configurationString);

Public Function Config(ByVal ConfigurationString As String) As String

Remarks

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

These settings are similar in functionality to properties, but they are rarely used. In order to avoid "polluting" the property namespace of the component, 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.

Interrupt Method (FDMSRegister Component)

Interrupts the current action.

Syntax

• C#
• VB.NET

public void Interrupt();

Public Sub Interrupt()

Remarks

This method interrupts any processing that the component is currently executing.

Ping Method (FDMSRegister Component)

Used to find the fastest service provider to use to send credit card transactions.

Syntax

• C#
• VB.NET

public void Ping(string url);

Public Sub Ping(ByVal url As String)

Remarks

The Ping request is used to determine which one of the ServiceProviders URLs is the most efficient to use for transaction transport. The Ping request verifies that the ServiceProviders URLs are reachable and provides the average transaction time cost for each URL, returned in the PingResponseTime property. You should select the fastest ServiceProviders URL to be the active URL that you will use to process all transactions. You should maintain a list of the other ServiceProviders URLs in a queue from fastest to slowest, in the event that the fastest URL becomes unavailable.

A Ping should be sent for each of the ServiceProviders URLs after every 100 authorizations, to ensure that you're still using the fastest URL. A Ping should be run on the ServiceProviders URLs any time the application is first started.

For example:

FDMSRegister.MerchantNumber = "000000999990"; FDMSRegister.MerchantTerminalNumber = "555555"; FDMSRegister.TransactionNumber = "0000001V002500"; //any unique number will do; check TransactionNumber property for format FDMSRegister.URL = "https://stagingsupport.datawire.net/staging_expresso/SRS.do"; FDMSRegister.Register(); FDMSRegister.TransactionNumber = "0000002V002500"; //any unique number will do; check TransactionNumber property for format FDMSRegister.Activate(); FDMSRegister.ServiceDiscovery(FDMSRegister.PrimaryDiscoveryURL); for (int i = 0; i < FDMSRegister.ServiceProviders.Length; i++) { FDMSRegister.Ping(FDMSRegister.ServiceProviders[i]); Console.WriteLine(FDMSRegister.ServiceProviders[i] + " = " + FDMSRegister.PingResponseTime); }

Note: This functionaly does not apply to Rapid Connect implementations.

Register Method (FDMSRegister Component)

Registers a merchant account on the Datawire VXN.

Syntax

• C#
• VB.NET

public void Register();

Public Sub Register()

Remarks

For the North, Nashville, and Omaha platforms: FDMS will supply you with a MerchantNumber, MerchantTerminalNumber, and Datawire will supply the URL to use to register your merchant. After setting the above properties, call the Register method. The Register method will send the registration request to Datawire, and will continue to poll the Datawire servers until a response is received. This may take several seconds, or even several minutes.

When the registration is complete, the registration response returns the merchant's DatawireId, and the PrimaryDiscoveryURL and SecondaryDiscoveryURL needed to perform ServiceDiscovery. Once received, these parameters must be saved permanently so that they can be reloaded and configured when necessary and are never lost due to power outages.

For example:

FDMSRegister.MerchantNumber = "000000999990"; FDMSRegister.MerchantTerminalNumber = "555555"; FDMSRegister.TransactionNumber = "0000001V002500"; //any unique number will do; check TransactionNumber property for format FDMSRegister.URL = "https://stagingsupport.datawire.net/staging_expresso/SRS.do"; FDMSRegister.Register(); FDMSRegister.TransactionNumber = "0000002V002500"; //any unique number will do; check TransactionNumber property for format FDMSRegister.Activate(); FDMSRegister.ServiceDiscovery(FDMSRegister.PrimaryDiscoveryURL); for (int i = 0; i < FDMSRegister.ServiceProviders.Length; i++) { FDMSRegister.Ping(FDMSRegister.ServiceProviders[i]); Console.WriteLine(FDMSRegister.ServiceProviders[i] + " = " + FDMSRegister.PingResponseTime); }

For the Rapid Connect platform: ServiceDiscovery will need to be performed first. After a successful ServiceDiscovery call, URL will be populated with the URL required to provision your merchant account. Once TransactionNumber and ApplicationId are set, Register can be called. The Register method will send the registration request to Datawire, and will continue to poll the Datawire servers until a response is received. This may take several seconds, or even several minutes.

When the registration is complete, the registration response returns the merchant's DatawireId, and the PrimaryDiscoveryURL and SecondaryDiscoveryURL needed to process transactions. Once received, these parameters must be saved permanently so that they can be reloaded and configured when necessary and are never lost due to power outages.

For example:

FDMSRegister.MerchantNumber = "000000999990"; FDMSRegister.MerchantTerminalNumber = "555555"; FDMSRegister.Config("GroupId=10001"); FDMSRegister.TransactionNumber = "0000001VRC1234"; //any unique number will do; check TransactionNumber property for format FDMSRegister.ServiceDiscovery("https://prod.dw.us.fdcnet.biz/sd/srsxml.rc"); FDMSRegister.ApplicationId = "RAPIDCONNECTSRS"; FDMSRegister.TransactionNumber = "0000002VRC1234" //any unique number will do; check TransactionNumber property for format FDMSRegister.Register(); FDMSRegister.TransactionNumber = "0000003VRC1234" //any unique number will do; check TransactionNumber property for format FDMSRegister.Activate();

Reset Method (FDMSRegister Component)

Clears all properties to their default values.

Syntax

• C#
• VB.NET

public void Reset();

Public Sub Reset()

Remarks

This method clears all properties to their default values.

ServiceDiscovery Method (FDMSRegister Component)

Retrieves transaction URLs from Datawire.

Syntax

• C#
• VB.NET

public void ServiceDiscovery(string url);

Public Sub ServiceDiscovery(ByVal url As String)

Remarks

Service Discovery is the means by which you retrieve the actual transaction URLs, used for making credit card authorizations and sending batch settlements.

For the North, Nashville, and Omaha platforms: The response to a successful call to the Register method will return a PrimaryDiscoveryURL and SecondaryDiscoveryURL. After the account has been activated, call the ServiceDiscovery method with either of these URLs as the URL parameter. A successful ServiceDiscovery will provide a list of Service Provider URL's necessary to transport transactions from the application through the Datawire VXN to the FDMS payment processor and back. This list of URL's returned will be stored in the ServiceProviders array property. You should Ping each of these URLs to determine which one has the shortest PingResponseTime, and use that URL for subsequent credit card transactions (note that you should re-Ping each of the URLs received in the ServiceProviders array every 100 transactions, and when first initializing your software).

For example:

FDMSRegister.MerchantNumber = "000000999990"; FDMSRegister.MerchantTerminalNumber = "555555"; FDMSRegister.TransactionNumber = "0000001V002500"; //any unique number will do; check TransactionNumber property for format FDMSRegister.URL = "https://stagingsupport.datawire.net/staging_expresso/SRS.do"; FDMSRegister.Register(); FDMSRegister.TransactionNumber = "0000002V002500"; //any unique number will do; check TransactionNumber property for format FDMSRegister.Activate(); FDMSRegister.ServiceDiscovery(FDMSRegister.PrimaryDiscoveryURL); for (int i = 0; i < FDMSRegister.ServiceProviders.Length; i++) { FDMSRegister.Ping(FDMSRegister.ServiceProviders[i]); Console.WriteLine(FDMSRegister.ServiceProviders[i] + " = " + FDMSRegister.PingResponseTime); }

For the Rapid Connect platform: ServiceDiscovery will be the first step in provisioning a merchant. FDMS will supply you with a MerchantNumber, MerchantTerminalNumber, and GroupId. After setting these properties, ServiceDiscovery should be called. The default URL, when URL parameter is set to "" (empty string), is "https://prod.dw.us.fdcnet.biz/sd/srsxml.rc". A successful ServiceDiscovery will provide the URL, accessible via URL, necessary to provision a merchant account.

For example:

FDMSRegister.MerchantNumber = "000000999990"; FDMSRegister.MerchantTerminalNumber = "555555"; FDMSRegister.Config("GroupId=10001"); FDMSRegister.TransactionNumber = "0000001VRC1234"; //any unique number will do; check TransactionNumber property for format FDMSRegister.ServiceDiscovery("https://prod.dw.us.fdcnet.biz/sd/srsxml.rc"); FDMSRegister.ApplicationId = "RAPIDCONNECTSRS"; FDMSRegister.TransactionNumber = "0000002VRC1234" //any unique number will do; check TransactionNumber property for format FDMSRegister.Register(); FDMSRegister.TransactionNumber = "0000003VRC1234" //any unique number will do; check TransactionNumber property for format FDMSRegister.Activate();

Connected Event (FDMSRegister Component)

This event is fired immediately after a connection completes (or fails).

Syntax

• C#
• VB.NET

public event OnConnectedHandler OnConnected;

public delegate void OnConnectedHandler(object sender, FdmsregisterConnectedEventArgs e);

public class FdmsregisterConnectedEventArgs : EventArgs {
  public int StatusCode { get; }
  public string Description { get; }
}

SSLServerAuthentication Event (FDMSRegister Component)

Fired after the server presents its certificate to the client.

Syntax

• C#
• VB.NET

public event OnSSLServerAuthenticationHandler OnSSLServerAuthentication;

public delegate void OnSSLServerAuthenticationHandler(object sender, FdmsregisterSSLServerAuthenticationEventArgs e);

public class FdmsregisterSSLServerAuthenticationEventArgs : EventArgs {
  public string CertEncoded { get; }
  public byte[] CertEncodedB { get; }
  public string CertSubject { get; }
  public string CertIssuer { get; }
  public string Status { get; }
  public bool Accept { get; set; }
}

Public Event OnSSLServerAuthentication As OnSSLServerAuthenticationHandler

Public Delegate Sub OnSSLServerAuthenticationHandler(sender As Object, e As FdmsregisterSSLServerAuthenticationEventArgs)

Public Class FdmsregisterSSLServerAuthenticationEventArgs Inherits EventArgs
  Public ReadOnly Property CertEncoded As String
  Public ReadOnly Property CertEncodedB As Byte()
  Public ReadOnly Property CertSubject As String
  Public ReadOnly Property CertIssuer As String
  Public ReadOnly Property Status As String
  Public Property Accept As Boolean
End Class

Remarks

During this event, the client can decide whether or not to continue with the connection process. The Accept parameter is a recommendation on whether to continue or close the connection. This is just a suggestion: application software must use its own logic to determine whether or not to continue.

When Accept is False, Status shows why the verification failed (otherwise, Status contains the string OK). If it is decided to continue, you can override and accept the certificate by setting the Accept parameter to True.

SSLStatus Event (FDMSRegister Component)

Fired when secure connection progress messages are available.

Syntax

Certificate Type

This is the digital certificate being used.

Remarks

This type describes the current digital certificate. The certificate may be a public or private key. The fields are used to identify or select certificates.

Fields

Constructors

• C#
• VB.NET

public Certificate();

Public Certificate()

Creates a Certificate instance whose properties can be set. This is useful for use with CERTMGR when generating new certificates.

• C#
• VB.NET

public Certificate(string certificateFile);

Public Certificate(ByVal CertificateFile As String)

Opens CertificateFile and reads out the contents as an X.509 public key.

• C#
• VB.NET

public Certificate(byte[] certificateData);

Public Certificate(ByVal CertificateData As Byte())

Parses CertificateData as an X.509 public key.

• C#
• VB.NET

public Certificate(CertStoreTypes certStoreType, string store, string storePassword, string subject);

Public Certificate(ByVal CertStoreType As CertStoreTypes, ByVal Store As String, ByVal StorePassword As String, ByVal Subject As String)

CertStoreType identifies the type of certificate store to use. See StoreType for descriptions of the different certificate stores. Store is a file containing the certificate store. StorePassword is the password used to protect the store. After the store has been successfully opened, the component will attempt to find the certificate identified by Subject . This can be either a complete or a substring match of the X.509 certificate's subject Distinguished Name (DN).

• C#
• VB.NET

public Certificate(CertStoreTypes certStoreType, string store, string storePassword, string subject, string configurationString);

Public Certificate(ByVal CertStoreType As CertStoreTypes, ByVal Store As String, ByVal StorePassword As String, ByVal Subject As String, ByVal ConfigurationString As String)

CertStoreType identifies the type of certificate store to use. See StoreType for descriptions of the different certificate stores. Store is a file containing the certificate store. StorePassword is the password used to protect the store. ConfigurationString is a newline separated list of name-value pairs that may be used to modify the default behavior. Possible values include "PersistPFXKey", which shows whether or not the PFX key is persisted after performing operations with the private key. This correlates to the PKCS12_NO_PERSIST_KEY CryptoAPI option. The default value is True (the key is persisted). "Thumbprint" - an MD5, SHA-1, or SHA-256 thumbprint of the certificate to load. When specified, this value is used to select the certificate in the store. This is applicable to cstUser, cstMachine, cstPublicKeyFile, and cstPFXFile store types. "UseInternalSecurityAPI" shows whether the platform (default) or the internal security API is used when performing certificate-related operations. After the store has been successfully opened, the component will attempt to find the certificate identified by Subject . This can be either a complete or a substring match of the X.509 certificate's subject Distinguished Name (DN).

• C#
• VB.NET

public Certificate(CertStoreTypes certStoreType, string store, string storePassword, byte[] encoded);

Public Certificate(ByVal CertStoreType As CertStoreTypes, ByVal Store As String, ByVal StorePassword As String, ByVal Encoded As Byte())

CertStoreType identifies the type of certificate store to use. See StoreType for descriptions of the different certificate stores. Store is a file containing the certificate store. StorePassword is the password used to protect the store. After the store has been successfully opened, the component will load Encoded as an X.509 certificate and search the opened store for a corresponding private key.

• C#
• VB.NET

public Certificate(CertStoreTypes certStoreType, byte[] storeBlob, string storePassword, string subject);

Public Certificate(ByVal CertStoreType As CertStoreTypes, ByVal StoreBlob As Byte(), ByVal StorePassword As String, ByVal Subject As String)

CertStoreType identifies the type of certificate store to use. See StoreType for descriptions of the different certificate stores. StoreBlob is a string (binary- or Base64-encoded) containing the certificate data. StorePassword is the password used to protect the store. After the store has been successfully opened, the component will attempt to find the certificate identified by Subject . This can be either a complete or a substring match of the X.509 certificate's subject Distinguished Name (DN).

• C#
• VB.NET

public Certificate(CertStoreTypes certStoreType, byte[] storeBlob, string storePassword, string subject, string configurationString);

Public Certificate(ByVal CertStoreType As CertStoreTypes, ByVal StoreBlob As Byte(), ByVal StorePassword As String, ByVal Subject As String, ByVal ConfigurationString As String)
