of X9 that ANSI X9.23-1995 no longer provides sufficient security to protect wholesale
financial transactions. Hence, X9.23 is being withdrawn.
This Guideline discusses:

Please do not misunderstand the intent of this guideline. Continue to use single DES
based X9.23 until a replacement is implemented. Until the replacement is implemented,
