Check21 Class

Properties Methods Events Config Settings Errors

The Check21 class is used to construct a file containing scanned images of paper checks, and optionally upload it to an FTPS server.

Syntax

inpay.Check21

Remarks

An X9.37 file created by this class will contain the following records:

File Header Record (1)
Cash Letter Header Record (1)
Bundle Header Record (1)
Check detail record structure (0 to Checks.Count), which contains:
- Check Detail Record (1)
- Check Detail Addenda A (1)
- Front Image View Detail Record (0 or 1)
- Front Image View Data Record (0 or 1)
- Back Image View Detail Record (0 or 1)
- Back Image View Data Record (0 or 1)
Bundle Control Record (1)
Cash Letter Control Record (1)
File Control Record (1)

This class makes creating the above file very easy. First set the Origin fields with information about the institution that is originating this file, and the destination it is to be deposited to. Also set the ReturnRoutingNumber. Check21.Origin.OriginName = "First Bank of Thor" Check21.Origin.RoutingNumber = "111012822" Check21.Origin.ContactName = "Jake Olsen" Check21.Origin.ContactPhone = "800-555-5555" Check21.DestinationRoutingNumber = "051000321" Check21.DestinationName = "First Bank of Loki" Check21.ReturnRoutingNumber = "111012822" This file must be differentiated from other files, so now set the CashLetterId and CycleNumber properties, as well as the Filename. (Alternatively Filename may be left empty, and the class will write the file to memory and store it in the FileData property).

Check21.CashLetterId = "123456" Check21.CycleNumber = "01" Check21.Filename = "sample_output.dat" This file is going to contain scanned images of paper checks, so RecordType should be set to rtChecksAndImages and make sure the DocumentationType is set to a compatible value ("G" through "J" are valid when RecordType is rtChecksAndImages). Check21.RecordType = rtChecksAndImages Check21.DocumentationType = "G" This sample file is to contain only one check, but a real file may contain any number of checks. To add a check, create a new CheckDetail object and fill the fields with information read off the check's MICR line, as well as the Payee's name and the amount of the check. CheckDetail check = new CheckDetail() check.MICROnUs = "1234567890101" ' Account number on the check check.MICRRoutingNumber = "902113700" check.Amount = "50000" ' $500.00 check.SequenceNumber = "407" check.PayeeName = "Bruce Banner" Then set information about the Bank of First Deposit. This may be identical to the Origin. The BOFDConversionIndicator should also be set to "2" if this bank converted the original check into the image being included. check.BOFDRoutingNumber = "111012822" check.BOFDAccountNumber = "181818181818181818" check.BOFDBranch = "Asgard" check.BOFDConversionIndicator = "2" Finally, you must include images of the front and back of the check, and indicate the format and compression used to create those images. You may use FrontImageFilename and BackImageFilename fields to point to image files on disk, or you may set the binary data directly in FrontImageData and BackImageData. You also need to set a unique identifier that can be used to retrieve the images at a later date. check.ImageFormat = ifTIFF ' default check.ImageCompression = icJPEG ' default check.CanRecreateImages = True ' default check.FrontImageFilename = "front.jpg" check.FrontImageReferenceKey = "72234215front" check.BackImageFilename = "back.jpg" check.BackImageReferenceKey = "72234215back" Finally add the check image to the class's Checks collection. Check21.Checks.Add(check) Now call BuildFile to build the file and save it to the Filename you indicated earlier. If you have an FTPS server (TLS/SSL-secured FTP) to upload the files to, you may set the FTP fields and call BuildAndUploadFile method instead.

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

Syntax


public Certificate getSSLAcceptServerCert();


public void setSSLAcceptServerCert(Certificate SSLAcceptServerCert);

Remarks

If it finds any issues with the certificate presented by the server, the class 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 (Check21 Class)

The certificate to be used during SSL negotiation.

Syntax


public Certificate getSSLCert();


public void setSSLCert(Certificate SSLCert);

Remarks

The digital certificate that the class 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 (Check21 Class)

This specifies the SSL/TLS implementation to use.

Syntax


public int getSSLProvider();


public void setSSLProvider(int SSLProvider);


Enumerated values:
  public final static int sslpAutomatic = 0;
  public final static int sslpPlatform = 1;
  public final static int sslpInternal = 2;

Default Value

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 class 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:


0 (sslpAutomatic - default)	Automatically selects the appropriate implementation.
1 (sslpPlatform)	Uses the platform/system implementation.
2 (sslpInternal)	Uses the internal implementation.

Additional Notes

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

When Automatic is selected the platform implementation is used by default. When TLS 1.3 is enabled via SSLEnabledProtocols the internal implementation is used.

SSLServerCert Property (Check21 Class)

The server certificate for the last established connection.

Syntax


public Certificate getSSLServerCert();

Remarks

SSLServerCert contains the server certificate for the last established connection.

SSLServerCert is reset every time a new connection is attempted.

  public final static int sslNone = 3;

Default Value

Remarks

The SSLStartMode property may have one of the following values:


0 (sslAutomatic)	If the remote port is set to the standard plaintext port of the protocol (where applicable), the class will behave the same as if SSLStartMode is set to sslExplicit. In all other cases, SSL negotiation will be implicit (sslImplicit).
1 (sslImplicit)	The SSL negotiation will start immediately after the connection is established.
2 (sslExplicit)	The class will first connect in plaintext, and then explicitly start SSL negotiation through a protocol command such as STARTTLS.
3 (sslNone - default)	No SSL negotiation, no SSL security. All communication will be in plaintext mode.

BuildAndUploadFile Method (Check21 Class)

Builds an X9.37 file and uploads it to an FTP server.

Syntax

public void buildAndUploadFile();

Remarks

This method builds a complete X9.37 file and uploads it to the server specified in the RemoteHost field. If an Filename is specified, it will be saved on the local disc as well. If Filename contains only a path (Filename must terminate in a "/" or "\"), that path will be used to create a temporary file which will be deleted after the upload. If Filename is empty, the system temp directory will be used for creating the temporary file.

An X9.37 file created by this class will contain the following records:

File Header Record (1)
Cash Letter Header Record (1)
Bundle Header Record (1)
Check detail record structure (0 to Checks.Count), which contains:

This method builds a complete X9.37 file. If the Filename is specified, the file will be saved to the path and filename indicated there. If no Filename is given, the resultant file will be stored in memory, and can be accessed in the FileData property.

An X9.37 file created by this class will contain the following records:

File Header Record (1)
Cash Letter Header Record (1)
Bundle Header Record (1)
Check detail record structure (0 to Checks.Count), which contains:
- Check Detail Record (1)

Bundle Control Record (1)
Cash Letter Control Record (1)
File Control Record (1)

Config Method (Check21 Class)

Sets or retrieves a configuration setting.

Syntax

public String config(String configurationString);

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.

DoEvents Method (Check21 Class)

Processes events from the internal message queue.

Syntax

public void doEvents();

Remarks

When DoEvents is called, the class processes any available events. If no events are available, it waits for a preset period of time, and then returns.

Interrupt Method (Check21 Class)

Interrupt the current method.

Syntax

public void interrupt();

Remarks

If there is no method in progress, Interrupt simply returns, doing nothing.

Reset Method (Check21 Class)

Reset the internal state of the class and all properties to their default values.

Syntax

public void reset();

Remarks

The Reset method doesn't have any parameters and doesn't return any value.

Error Event (Check21 Class)

Information about non-fatal errors encountered during file construction.

Syntax

public class DefaultCheck21EventListener implements Check21EventListener {
  ...
  public void error(Check21ErrorEvent e) {}
  ...
}

public class Check21ErrorEvent {
  public int errorCode;
  public String description;
}

Remarks

The Error event is fired to warn the user that it may be operating differently than the user expects. For instance, if the CollectionType is set to ctNoDetail, but check detail records are provided in the Checks collection the class will fire this event indicating that the specified Checks were ignored.

ErrorCode contains an error code and Description contains a textual description of the error. For a list of valid error codes and their descriptions, please refer to the Error Codes section.

SSLServerAuthentication Event (Check21 Class)

Fired after the server presents its certificate to the client.

Syntax

public class DefaultCheck21EventListener implements Check21EventListener {
  ...
  public void SSLServerAuthentication(Check21SSLServerAuthenticationEvent e) {}
  ...
}

public class Check21SSLServerAuthenticationEvent {
  public byte[] certEncoded;
  public String certSubject;
  public String certIssuer;
  public String status;
  public boolean accept;
}

Remarks

This event is where the client can decide whether to continue with the connection process or not. 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 to continue or not.

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 (Check21 Class)

Shows the progress of the secure connection.

Syntax

public class DefaultCheck21EventListener implements Check21EventListener {
  ...
  public void SSLStatus(Check21SSLStatusEvent e) {}
  ...
}

public class Check21SSLStatusEvent {
  public String message;
}

Remarks

The event is fired for informational and logging purposes only. Used to track the progress of the connection.

Status Event (Check21 Class)

Traces the commands sent to the server, and the respective replies.

Syntax

public class DefaultCheck21EventListener implements Check21EventListener {
  ...
  public void status(Check21StatusEvent e) {}
  ...
}

public class Check21StatusEvent {
  public String message;
}

Remarks

The Status event is useful for debugging purposes. It shows all the interaction between the client and the server, line by line.

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

EffectiveDate
String

This is the date on which this certificate becomes valid. Before this date, it is not valid. The following example illustrates the format of an encoded date:

23-Jan-2000 15:00:00.

Encoded
String

This is the certificate (PEM/base64 encoded). This field is used to assign a specific certificate. The Store and Subject fields also may be used to specify a certificate.

When Encoded is set, a search is initiated in the current Store for the private key of the certificate. If the key is found, Subject is updated to reflect the full subject of the selected certificate; otherwise, Subject is set to an empty string.

EncodedB
byte[]

This is the certificate (PEM/base64 encoded). This field is used to assign a specific certificate. The Store and Subject fields also may be used to specify a certificate.

ExpirationDate
String

This is the date the certificate expires. After this date, the certificate will no longer be valid. The following example illustrates the format of an encoded date:

23-Jan-2001 15:00:00.

ExtendedKeyUsage
String

This is a comma-delimited list of extended key usage identifiers. These are the same as ASN.1 object identifiers (OIDs).

Fingerprint
String

This is the hex-encoded, 16-byte MD5 fingerprint of the certificate. This property is primarily used for keys which do not have a corresponding X.509 public certificate, such as PEM keys that only contain a private key. It is commonly used for SSH keys.

The following example illustrates the format: bc:2a:72:af:fe:58:17:43:7a:5f:ba:5a:7c:90:f7:02

FingerprintSHA1
String

This is the hex-encoded, 20-byte SHA-1 fingerprint of the certificate. This property is primarily used for keys which do not have a corresponding X.509 public certificate, such as PEM keys that only contain a private key. It is commonly used for SSH keys.

The following example illustrates the format: 30:7b:fa:38:65:83:ff:da:b4:4e:07:3f:17:b8:a4:ed:80:be:ff:84

FingerprintSHA256
String

This is the hex-encoded, 32-byte SHA-256 fingerprint of the certificate. This property is primarily used for keys which do not have a corresponding X.509 public certificate, such as PEM keys that only contain a private key. It is commonly used for SSH keys.

The following example illustrates the format: 6a:80:5c:33:a9:43:ea:b0:96:12:8a:64:96:30:ef:4a:8a:96:86:ce:f4:c7:be:10:24:8e:2b:60:9e:f3:59:53

Issuer
String

This is the issuer of the certificate. This field contains a string representation of the name of the issuing authority for the certificate.

KeyPassword
String

This is the password for the certificate's private key (if any).

Some certificate stores may individually protect certificates' private keys, separate from the standard protection offered by the StorePassword. KeyPassword. This field can be used to read such password-protected private keys.

Note: this property defaults to the value of StorePassword. To clear it, you must set the property to the empty string (""). It can be set at any time, but when the private key's password is different from the store's password, then it must be set before calling PrivateKey.

PrivateKey
String

This is the private key of the certificate (if available). The key is provided as PEM/Base64-encoded data.

Note: The PrivateKey may be available but not exportable. In this case, PrivateKey returns an empty string.

PrivateKeyAvailable
boolean

This field shows whether a PrivateKey is available for the selected certificate. If PrivateKeyAvailable is True, the certificate may be used for authentication purposes (e.g., server authentication).

PrivateKeyContainer
String

This is the name of the PrivateKey container for the certificate (if available). This functionality is available only on Windows platforms.

PublicKey
String

Base Config Settings

BuildInfo: Information about the product's build.

When queried, this setting will return a string containing information about the product's build.

GUIAvailable: Tells the class whether or not a message loop is available for processing events.

In a GUI-based application, long-running blocking operations may cause the application to stop responding to input until the operation returns. The class will attempt to discover whether or not the application has a message loop and, if one is discovered, it will process events in that message loop during any such blocking operation.

In some non-GUI applications, an invalid message loop may be discovered that will result in errant behavior. In these cases, setting GUIAvailable to false will ensure that the class does not attempt to process external events.

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.

UseDaemonThreads: Whether threads created by the class are daemon threads.

If set to True (default), when the class creates a thread, the thread's Daemon property will be explicitly set to True. When set to False, the class will not set the Daemon property on the created thread. The default value is True.

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.

This setting is set to false by default on all platforms.
