Encrypted_PIN_Translate CCA Release 2.54
key serial number, and then uses ANSI X9.24-specified “special decryption.”
Checks the control vector to ensure that for an IPINENC key that the
TRANSLAT bit is valued to one for translate mode and/or the REFORMAT bit is
valued to one for reformat mode, or for a KEYGENKY key that the UKPT bit is
valued to one. Likewise the OPINENC key must have one or both of the
TRANSLAT and REFORMAT bits set appropriate to the requested mode.
In reformat mode, the verb performs these additional steps:
– Extracts the PIN from the specified PIN-block format using the method
specified by default or by a rule-array keyword. If required by the
PIN-block format, PAN data will be used in the extraction process.
– Formats the extracted-PIN into the format declared for the output
PIN-block. As required by the PIN-block format, the verb incorporates PAN
data, sequence number, and pad character information in formatting the
output.
Encrypts the output PIN-block by using the supplied OPINENC key in ECB
mode, or derives the decryption key using the specified KEYGENKY key and
output current key serial number and uses ANSI X9.24-specified “special
encryption.” The TRANSLAT bit must be valued to one in the OPINENC control
vector, or the UKPT bit must be valued to one in the KEYGENKY control
vector.
Restrictions
Some CCA implementations may enforce a specific order of the rule array
keywords with this verb; see product-specific literature.
Previous editions of this manual incorrectly described the CKSN as requiring
space-character padding. Pad the CKSN with four bytes of X'00'.
