MASK

Create a token without inserting it in the database.

Import Parameters

• ITOKENGEN - Allows users to create custom tokenization functions that define the way data is tokenized.

  Following code snippet explains the procedure of implementing itokengenerator:

  1. There is an interface in the CT-V jarfile.

     public interface com.safenet.token.ITokenGenerator
     {
     public String generateToken( String value ) throws TokenException;
     }
     

  2. Define a class that implements the interface.

     package com.customer.code.tokenizers;
     class MyTokenizer implements com.safenet.token.ITokenGenerator
     {
         String generateToken( String value ) throws TokenException
             {
                 // For simplicity, defers to customer tokenizer function.
                 return tokenizeFunction( value );
             }
     }
     

  3. Create a jar and place it in the <SAP Binaries>\lib\classes.

     Note

     <SAP Binaries> is the location set during installation. Refer to Installing SAP Binaries for details.

  4. Restart the SAPTM windows service.

  5. Enter the value for this parameter as: com.customer.code.tokenizers.MyTokenizer.

     From the common parameters, refer to the source code below for exact parameters.
