EDIFACTWriter Class

Properties   Methods   Events   Config Settings   Errors  

The EDIFACTWriter class is optimized for EDIFACT documents, providing a simple way to create EDIFACT documents.

Syntax

ipworkseditranslator.Edifactwriter

Remarks

The class allows you to create a document from scratch. The class allows you to create an EDI document one segment at a time. Here's how a document would normally be created:

  1. Call LoadSchema to load the necessary schemas for the transactions that will be used.
  2. Specify where to write the output document by setting the OutputFile property or SetOutputStream method, or set neither and check the OutputData property.
  3. Create a new interchange start segment using the StartInterchangeHeader method and set its properties using WriteElementString and WriteComponentString.
  4. To write a basic element value to the current location, call the WriteElementString method. For complex element values, there are two possibilities, elements which are split into components, and elements which repeat. To write these complex element values, use the StartElement and EndElement methods, with WriteComponentString and RepeatElement methods for writing the values. (Examples available below).
  5. Create a new functional group using StartFunctionalGroupHeader and set its properties using WriteElementString and WriteComponentString.
  6. Create a new transaction using StartTransactionHeader and set the properties for the header segment.
  7. Write all the data for the transaction by creating new data segments using StartSegment and providing the path of the segment to create using the schema names of the loops and segments, like /N1Loop1/N1.
  8. Once you are done with the segment, call EndSegment.
  9. Once you are done with the transaction, call CreateTransactionFooter.
  10. Once you are done with the functional group, call CreateFunctionalGroupFooter.
  11. Once the interchange is complete, call CreateInterchangeFooter.

Example EDIFACTWriter Code:

EDIWriter1.StartInterchangeHeader("D98B"); //Complex Element, two components EDIWriter1.StartElement(); EDIWriter1.WriteComponentString("UNOB"); EDIWriter1.WriteComponentString("1"); EDIWriter1.EndElement(); //Skip a value for this element EDIWriter1.SkipElement(); //Basic element EDIWriter1.WriteElementString("7654323"); ... EDIWriter1.StartFunctionalGroupHeader(); ... EDIWriter1.StartTransactionHeader("APERAK"); //Complex Element, repeated element EDIWriter1.StartElement(); EDIWriter1.WriteComponentString("UNH1"); EDIWriter1.RepeatElement(); EDIWriter1.WriteComponentString("UNH2"); EDIWriter1.EndElement(); ... //Segment and its data EDIWriter1.StartSegment("BGM"); EDIWriter1.StartElement(); EDIWriter1.WriteComponentString("C00"); EDIWriter1.EndElement(); EDIWriter1.StartElement(); EDIWriter1.WriteComponentString("C10601"); EDIWriter1.EndElement(); EDIWriter1.EndSegment(); ... CreateTransactionFooter(); CreateFunctionalGroupFooter(); CreateInterchangeFooter();

FileWriteMode Property (EDIFACTWriter Class)

Controls how the output file is opened.

Syntax


public int getFileWriteMode();


public void setFileWriteMode(int fileWriteMode);


Enumerated values:
  public final static int fwmCreate = 0;
  public final static int fwmOverwrite = 1;
  public final static int fwmAppend = 2;

Default Value

0

Remarks

This property controls how the component will open the output file specified in OutputFile. Possible values are:

fwmCreate (0)Always create a new file. If the file already exists, an error will be raised.
fwmOverwrite (1)If the output file already exists, it will be overwritten.
fwmAppend (2)If the output file already exists, data will be appended to it.

OutputData Property (EDIFACTWriter Class)

Contains the output data.

Syntax


public byte[] getOutputData();


Default Value

""

Remarks

This property will be populated with the contents of the EDI data as output by the class when no OutputFile has been specified and SetOutputStream has not been called with a valid output stream.

This property is read-only.

OutputFile Property (EDIFACTWriter Class)

Specifies the name of the EDI file to write to.

Syntax


public String getOutputFile();


public void setOutputFile(String outputFile);

Default Value

""

Remarks

Set OutputFile before calling the StartInterchangeHeader method to write an EDI interchange to a file on disk.

SchemaFormat Property (EDIFACTWriter Class)

The format of the schema file.

Syntax


public int getSchemaFormat();


public void setSchemaFormat(int schemaFormat);


Enumerated values:
  public final static int schemaAutomatic = 0;
  public final static int schemaBinary = 1;
  public final static int schemaBizTalk = 2;
  public final static int schemaSEF = 3;
  public final static int schemaBOTS = 4;
  public final static int schemaAltova = 5;
  public final static int schemaJSON = 6;

Default Value

0

Remarks

Set SchemaFormat before calling the LoadSchema method to specify the loading schema format.

The following schema formats are supported:

0 (schemaAutomatic - default) The schema type is automatically determined based on file extension.
1 (schemaBinary) A binary schema that was previously compiled by calling CompileSchema.
2 (schemaBizTalk) BizTalk (XSD): http://msdn.microsoft.com/en-us/library/aa559426(v=BTS.70).aspx
3 (schemaSEF) TIBCO Standard Exchange Format (SEF): https://docs.tibco.com/products/tibco-foresight-edisim-6-18-0
5 (schemaAltova) Altova: http://www.altova.com/
6 (schemaJSON) JSON

Suffix Property (EDIFACTWriter Class)

What to append after each segment delimiter.

Syntax


public int getSuffix();


public void setSuffix(int suffix);


Enumerated values:
  public final static int suffixNone = 0;
  public final static int suffixCR = 1;
  public final static int suffixLF = 2;
  public final static int suffixCRLF = 3;

Default Value

0

Remarks

If Suffix is different from suffixNone, trailing (suffix) characters are appended after each segment delimiter. This is useful if you want to have a carriage return/line feed after each segment to make the document more readable.

This property is not available at design time.

CompileSchema Method (Edifactwriter Class)

Compiles an existing XSD schema into an optimized binary representation.

Syntax

public void compileSchema(String xsdSchema, String binSchema);

Remarks

This method parses XsdSchema and generates an optimized binary representation that is saved into the path referenced by BinSchema. Binary schemas are smaller and require less resources when loading later using LoadSchema

If the schema file does not exists or cannot be parsed as an EDI schema, the component throws an exception.

Config Method (Edifactwriter 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.

CreateFunctionalGroupFooter Method (Edifactwriter Class)

Closes the current functional group by writing its footer segment.

Syntax

public void createFunctionalGroupFooter();

Remarks

The CreateFunctionalGroupFooter method will write any existing segments to the output stream and then generate and write the functional group closing segment (GE or UNE). If there is an open transaction set, CreateFunctionalGroupFooter will first call CreateTransactionFooter to close it. If there is no functional group open, an exception will be thrown.

CreateInterchangeFooter Method (Edifactwriter Class)

Closes the current interchange by writing its footer segment.

Syntax

public void createInterchangeFooter();

Remarks

The CreateInterchangeFooter method will write any existing segments to the output stream and then generate and write the interchange closing segment (IEA or UNZ). If there is an open transaction set, CreateInterchangeFooter will first call CreateTransactionFooter to close it. If there is an open functional group, CreateInterchangeFooter will first call CreateFunctionalGroupFooter to close it. If there is no interchange open, an exception will be thrown.

CreateTransactionFooter Method (Edifactwriter Class)

Closes the current transaction set by writing its footer segment.

Syntax

public void createTransactionFooter();

Remarks

The CreateTransactionFooter method will write any existing segments to the output stream and then generate and write the transaction set closing segment (SE or UNT). If there are no open transaction sets, an exception will be thrown.

DisplaySchemaInfo Method (Edifactwriter Class)

Returns a string showing the structure of the schema defining the document.

Syntax

public String displaySchemaInfo();

Remarks

After calling LoadSchema this may be called to obtain information about the structure of the schema defining the document. If the desired XPath is not known this helps determine the structure so that the correct XPath can be built.

Note: A valid schema must be loaded via LoadSchema.

For instance: Console.WriteLine(component.DisplaySchemaInfo()); Will output text like:

EndElement Method (Edifactwriter Class)

Finishes the current composite data element.

Syntax

public void endElement();

Remarks

Call EndElement once you've written all components in an element started with StartElement. You should not call this if you wrote a simple element using WriteElementString

EndSegment Method (Edifactwriter Class)

Ends writing the current segment.

Syntax

public void endSegment();

Remarks

EndSegment terminates writing the current segment and flushes it to the output stream/file.

You should call EndSegment to close a segment started with StartSegment, StartInterchangeHeader, StartFunctionalGroupHeader or StartTransactionHeader.

Flush Method (Edifactwriter Class)

Forces any pending segments to be written to the output stream without closing it.

Syntax

public void flush();

Remarks

The Flush method forces the component to write the last created segment to the output stream and then flush the output stream.

LoadSchema Method (Edifactwriter Class)

Loads a schema file describing a Transaction Set.

Syntax

public void loadSchema(String fileName);

Remarks

This method parses the File and loads it into an internal schema list. The class will attempt to automatically detect the SchemaFormat.

If the schema file does not exist or cannot be parsed as an EDI schema, the class throws an exception.

LoadSchemaStream Method (Edifactwriter Class)

Loads a schema stream describing a Transaction Set.

Syntax

public void loadSchemaStream(java.io.InputStream schemaStream);

Remarks

Parses Stream and loads it into an internal schema list. The SchemaFormat property must be set before calling this method.

The following SchemaFormat values are supported when calling this method:

  • schemaBinary
  • schemaBizTalk
  • schemaSEF
All other schema formats are unsupported when using this method. LoadSchema may be used if an unsupported schema format is required.

RepeatElement Method (Edifactwriter Class)

Adds a new repetition to the current element.

Syntax

public void repeatElement();

Remarks

RepeatElement is used to write repeated data elements in supporting version of X12 or EDIFACT. To use it, first write the first repetition of the simple or composite data element and then call RepeatElement to repeat it, then write again.

Example: Repeating a simple data element: EDIWriter writer = new EDIWriter(); ... writer.StartSegment("Tag"); ... writer.WriteElementString("R1_1"); writer.RepeatElement(); writer.WriteElementString("R1_2"); writer.RepeatElement(); writer.WriteElementString("R1_3"); ... writer.EndSegment();

Example: Repeating a composite data element: EDIWriter writer = new EDIWriter(); ... writer.StartSegment("Tag"); ... writer.StartElement(); writer.WriteComponentString("C1_1"); writer.WriteComponentString("C2_1"); writer.RepeatElement(); writer.WriteComponentString("C1_2"); writer.WriteComponentString("C2_2"); writer.RepeatElement(); writer.WriteComponentString("C1_3"); writer.EndElement(); ... writer.EndSegment();

Reset Method (Edifactwriter Class)

Resets the state of the control.

Syntax

public void reset();

Remarks

Resets the state of the writer. If a document has been partially written already, it will not be closed correctly and the write process will be aborted.

SetOutputStream Method (Edifactwriter Class)

An output stream to write the EDI data to.

Syntax

public void setOutputStream(java.io.OutputStream outputStream);

Remarks

Call SetOutputStream with a valid output stream before calling the StartInterchangeHeader method to write an EDI interchange directly to a stream.

SkipComponent Method (Edifactwriter Class)

Moves to the next sub-element in the current composite element in the current segment.

Syntax

public void skipComponent();

Remarks

SkipComponent can be used to avoid providing a value for the current sub-element in the opened composite element within the current segment.

If the sub-element already has a value (such as one provided by default by the class), said value will not be overwritten.

SkipElement Method (Edifactwriter Class)

Moves to the next data element in the current segment.

Syntax

public void skipElement();

Remarks

SkipElement can be used to avoid providing a value for the current element in the current segment.

If the element already has a value (such as one provided by default by the class), said value will not be overwritten.

StartElement Method (Edifactwriter Class)

Starts a new EDI composite data element on the current segment.

Syntax

public void startElement();

Remarks

When called, a new composite data element is created in the current segment. You can then call WriteComponentString one or more times to write the individual components or subelements that make up this composite.

Call EndElement once you've written all components in this element.

StartFunctionalGroupHeader Method (Edifactwriter Class)

Creates a new EDI functional group header segment on the current document.

Syntax

public void startFunctionalGroupHeader();

Remarks

When called, a new functional group start (GS or UNG) segment is created and set as the current segment. You should then set the values on said segment before adding a new transaction set within the document.

StartInterchangeHeader Method (Edifactwriter Class)

Creates a new EDI Interchange header segment on the current document.

Syntax

public void startInterchangeHeader(String version);

Remarks

When called, a new interchange start (ISA or UNB) segment is created and set as the current segment. You should then set the values on said segment before creating a functional group or a new transaction set within the document.

StartSegment Method (Edifactwriter Class)

Creates a new EDI data segment on the current document.

Syntax

public void startSegment(String segmentType);

Remarks

When called, a new data segment is created in the current transaction and set as the current segment. You can then set the values on said segment. Creating a new data segment automatically writes the previous current segment to the output stream.

The SegmentType argument specifies the type of data segment to create, using an XPath-like syntax, based on the transaction set schema. For example, to create a new N1 segment on the first N1 loop, specify "/N1Loop1/N1".

It's important to realize that segments must be created in the same order they should appear on the target EDI document. The EDIWriter component doesn't automatically enforce ordering rules, nor does it force the document to reorder segments in loops automatically.

StartTransactionHeader Method (Edifactwriter Class)

Creates a new EDI transaction set header on the current document.

Syntax

public void startTransactionHeader(String code);

Remarks

When called, a new transaction set start (ST or UNH) segment is created and set as the current segment. You should then set the values on said segment before adding creating transaction data segments.

The Code argument should specify the transaction code you want to create (for example, "850" or "INVOIC"). This value, together with the EDI specification and the version provided in the StartInterchangeHeader method are used to locate a matching transaction set schema on the components schema cache. You must make sure that a corresponding schema has been successfully loaded into the component by using the LoadSchema method before trying to call StartTransactionHeader.

WriteComponentString Method (Edifactwriter Class)

Sets the value of the next class within the current element in the current segment.

Syntax

public void writeComponentString(String value);

Remarks

Use the WriteComponentString method to specify a value for an individual component within a composite data element.

To write an entire composite data element, first call the StartElement method, then do one or more calls to WriteComponentString. Finish the composite element by calling the EndElement method.

WriteElementString Method (Edifactwriter Class)

Sets a value of the next element in the current segment to a simple value.

Syntax

public void writeElementString(String value);

Remarks

Use the WriteElementString method to specify a value for the next data element with simple content on the current segment.

To write a composite data element, even if it has a single sub-element, use the StartElement and WriteComponentString methods instead.

WriteTransaction Method (Edifactwriter Class)

Writes an entire transaction to the output.

Syntax

public void writeTransaction(String value);

Remarks

Use the WriteTransaction method when you have generated a complete transaction outside of the class and want to include it in the document being created by this instance.

No validation is done on the contents of the Value parameter. You must ensure the transaction data is valid and matches the same conventions (delimiters, etc) being used in this document.

Error Event (Edifactwriter Class)

Fired when information is available about errors during data delivery.

Syntax

public class DefaultEdifactwriterEventListener implements EdifactwriterEventListener {
  ...
  public void error(EdifactwriterErrorEvent e) {}
  ...
}

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

Remarks

The Error event is fired in case of exceptional conditions during message processing. Normally the class throws an exception.

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

Output Event (Edifactwriter Class)

Fires whenever a segment is complete.

Syntax

public class DefaultEdifactwriterEventListener implements EdifactwriterEventListener {
  ...
  public void output(EdifactwriterOutputEvent e) {}
  ...
}

public class EdifactwriterOutputEvent {
  public byte[] outputData;
}

Remarks

The Output event will fire when the writer completes a new segment and writes data to the output stream or buffer. The Data parameter contains the data bytes.

Warning Event (Edifactwriter Class)

Fires whenever a validation warning is encountered.

Syntax

public class DefaultEdifactwriterEventListener implements EdifactwriterEventListener {
  ...
  public void warning(EdifactwriterWarningEvent e) {}
  ...
}

public class EdifactwriterWarningEvent {
  public int warnCode;
  public String message;
  public int segmentNumber;
  public String segmentTag;
  public String segmentErrorCode;
  public String elementErrorCode;
  public int elementPosition;
}

Remarks

The Warning event will fire if a validation error is encountered when writing a new segment to the output document. The WarnCode parameter contains the type of warning encountered. Message is a textual description of the problem. SegmentNumber is the index of the segment where the problem was found.

0 The component is not required but is present.
1 Invalid segment count.
2 Invalid transaction count.
3 Invalid group count.
4 Invalid interchange control number.
5 Invalid group control number.
6 Invalid transaction control number.
10 A required data element is missing.
11 Invalid field length.
12 Invalid field value.
13 A required component is missing.
14 The data element is not defined but is present.
30 Required segment is missing.
31 Required loop is missing.
32 Occurrences exceeds the schema defined limit.
33 Occurrences is less than the schema defined minimum.
40 Paired rule validation failed, the pair of elements must be present.
41 At least one of element is required, see message for list of elements.
42 Exclusion validation failed, only one of the elements can be present.
43 Conditional rule validation failed.
44 List conditional rule validation failed.
45 First then none validation failed. The presence of an element requires that other specific elements must not be present.
46 Only one or none of the elements can be present.

Config Settings (Edifactwriter Class)

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.

EDIFACTWriter Config Settings

CloseStreamAfterInterchange:   Controls when the output stream is closed.

If True, the class will close the output stream when CreateInterchangeFooter is called. If false, the stream is left open and Flush must be called to ensure all output has been written to the stream. The default value is false.

ComponentDelimiter:   The delimiter character to use to separate components.

When set, this changes the default delimiter to use to separate components within a data element. The default value depends on the EDI specification being used.

EdifactSyntaxVersion:   Changes the syntax version used for EDIFACT control segments.

Can be a number from 1 to 4. The default value is 1.

EDIStandard:   The document format.

This property specifies standard that the document follows. Possible values are:

  • 1 (EDIFACT - default)
  • 3 (TRADACOMS)

ElementDelimiter:   The delimiter character to use to separate data elements.

When set, this changes the default delimiter to use to separate data elements within a segment. The default value depends on the EDI specification being used.

Encoding:   The character encoding to be applied when reading and writing data.

If the data contains non-ASCII characters this setting should be specified so characters are properly preserved. This value should be set to a valid character set such as "UTF-8" or "ISO-8859-1".

IncludeUNA:   Whether to include the UNA segment in the output.

This setting determines whether the UNA segment is included in the EDIFACT output. If False, no Service String Advice (UNA) segment will be generated for EDIFACT interchanges. The default value is True.

ReleaseChar:   The character to use to escape delimiters within values.

When set, this changes the default escape character. The default value depends on the EDI specification being used.

RepetitionChar:   The repetition character.

When set, this changes the default repetition character. The default value depends on the EDI specification being used.

SegmentDelimiter:   The delimiter character to use to separate segments.

When set, this changes the default delimiter to use to separate segments within an EDI document. The default value depends on the EDI specification being used.

StrictSchemaValidation:   Specifies the behavior during schema validation.

This setting specifies what happens when performing schema validation and a validation warning occurs. By default this value is set to 1 (Warn) and the Warning event will fire, but processing will not stop. See the WarnCode parameter list in the Warning event for details about possible validation warnings. Possible values for this setting are:

0 (Ignore) All validation warnings will be ignored. Warning will not fire with warnings.
1 (Warn - default) The Warning event will fire with all validation warnings.
2 (Error) All validation warnings are treated as errors and will cause an exception. Processing will stop immediately.
TransactionOnly:   Ignores interchange and functional group validation, allowing you to build the transaction body.

When set to true, interchange and functional group headers will not be required. This allows building of the transaction level of an EDIFact document without specifying a document type.

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:   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.

UseFIPSCompliantAPI:   Tells the class whether or not to use FIPS certified APIs.

When set to true, the class will utilize the underlying operating system's certified APIs. Java editions, regardless of OS, utilize Bouncy Castle FIPS, while all the other Windows editions make use of Microsoft security libraries.

The Java edition requires installation of the FIPS certified Bouncy Castle library regardless of the target operating system. This can be downloaded from https://www.bouncycastle.org/fips-java/. Only the "Provider" library is needed. The jar file should then be installed in a JRE search path.

In the application where the component will be used the following classes must be imported:

import java.security.Security; import org.bouncycastle.jcajce.provider.BouncyCastleFipsProvider;

The Bouncy Castle provider must be added as a valid provider and must also be configured to operate in FIPS mode:

System.setProperty("org.bouncycastle.fips.approved_only","true"); Security.addProvider(new BouncyCastleFipsProvider());

When UseFIPSCompliantAPI is true, SSL enabled classes can optionally be configured to use the TLS Bouncy Castle library. When SSLProvider is set to sslpAutomatic (default) or sslpInternal an internal TLS implementation is used, but all cryptographic operations are offloaded to the BCFIPS provider in order to achieve FIPS compliant operation. If SSLProvider is set to sslpPlatform the Bouncy Castle JSSE will be used in place of the internal TLS implementation.

To enable the use of the Bouncy Castle JSSE take the following steps in addition to the steps above. Both the Bouncy Castle FIPS provider and the Bouncy Castle JSSE must be configured to use the Bouncy Castle TLS library in FIPS mode. Obtain the Bouncy Castle TLS library from https://www.bouncycastle.org/fips-java/. The jar file should then be installed in a JRE search path.

In the application where the component will be used the following classes must be imported:

import java.security.Security; import org.bouncycastle.jcajce.provider.BouncyCastleFipsProvider; //required to use BCJSSE when SSLProvider is set to sslpPlatform import org.bouncycastle.jsse.provider.BouncyCastleJsseProvider;

The Bouncy Castle provider must be added as a valid provider and must also be configured to operate in FIPS mode:

System.setProperty("org.bouncycastle.fips.approved_only","true"); Security.addProvider(new BouncyCastleFipsProvider()); //required to use BCJSSE when SSLProvider is set to sslpPlatform Security.addProvider(new BouncyCastleJsseProvider("fips:BCFIPS")); //optional - configure logging level of BCJSSE Logger.getLogger("org.bouncycastle.jsse").setLevel(java.util.logging.Level.OFF); //configure the class to use BCJSSE component.setSSLProvider(1); //platform component.config("UseFIPSCompliantAPI=true"); Note: TLS 1.3 support requires the Bouncy Castle TLS library version 1.0.14 or later.

FIPS mode can be enabled by setting the UseFIPSCompliantAPI configuration setting to true. This is a static setting which applies to all instances of all classes of the toolkit within the process. It is recommended to enable or disable this setting once before the component has been used to establish a connection. Enabling FIPS while an instance of the component is active and connected may result in unexpected behavior.

For more details please see the FIPS 140-2 Compliance article.

Note: Enabling FIPS-compliance requires a special license; please contact sales@nsoftware.com for details.

UseInternalSecurityAPI:   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 configuration 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.
