TokenSpec

TokenSpec allows users to set the parameters based on which the plaintext is tokenized/detokenized. The five parameters of TokenSpec are:

• groupID: This parameter sets the group ID (long) for the plaintext to be tokenized. Different tokens will be generated for the same plaintext having different group IDs. The default value is set to 0.

• luhnCheck: This parameter determines if the luhn digit of the token generated should pass or fail the luhnCheck. The possible values for luhncheck are true or false. If no value is specified then CADP for Java does not luhn validate the generated token. If true or false is specified for this parameter, the input plaintext should also have a valid luhn digit.

• nonIdempotentTokens: This parameter determines if the same or different tokens are generated for the same input plaintext. If the value is set to true, CADP for Java may generate different tokens even if same input plaintext is tokenized again and again. If the value is set to false, CADP for Java will generate the same token for the same input plaintext each time it is tokenized. The default value is set to false.

• clearTextSensitive: This parameter determines if the digits in the clear-text position of the input plaintext is used to generate the token. For enhanced security, user can set the value to true. The default value is false. If Token_ALL format is used, the clearTextSensitive parameter is not applicable.

• format: This parameter allows user to set the structure of the token generated. Following Special characters @_:%+!/( ).;,‘ including spaces in the plaintext are retained in the generated token. The supported formats are:

  Formats	Description
  TOKEN_ALL	Creates a token in which all digits/alphabets of the input plaintext are replaced with random digits/alphabets.This is the default format. Example input plaintext: abc_123@gmail.com token generated: CLS_040@xpiiS.oEv
  LAST_FOUR_TOKEN	Creates a token that retains the last four original characters of the input plaintext.
  FIRST_SIX_TOKEN	Creates a token that retains the first six original characters of the input value.
  FIRST_TWO_LAST_FOUR_TOKEN	Creates a token that retains the first two and last four original characters of the input plaintext.
  FIRST_FOUR_LAST_FOUR_TOKEN	Creates a token that retains the first four and last four original characters of the input plaintext.
  FIRST_SIX_LAST_FOUR_TOKEN	Creates a token that retains the first six and last four original characters of the input plaintext.
