Description

CKM_DES3_X919_MAC and CKM_DES3_X919_MAC_GENERAL are signature generation and verification mechanisms, as defined by ANSI X9.19.  They are an extension of the single length key MAC mechanisms.  The data is MAC’ed with the left most key value in the normal manner, but the final cipher block is then decrypted (ECB mode) with the middle key value and encrypted (ECB mode) with the Right most key part.

For double length keys, the Right key component is the same as the Left key component.
