Mechanism description
Single DES-OFB64 denoted CKM_DES_OFB64 is a mechanism for single and multiple part encryption and decryption; based on DES Output Feedback Mode.
It has a parameter, an 8-byte initialization vector.
This mechanism does not require either clear text or ciphertext to be presented in multiple block lengths. There is no padding required. The mechanism will always return a reply equal in length to the request.
