Description
The SEED key generation mechanism, denoted CKM_SEED_KEY_GEN
, is a key generation mechanism for the Korean Information Security Agency’s SEED algorithm.
The mechanism does not have a parameter, and it generates SEED keys 16 bytes in length.
The mechanism contributes the CKA_CLASS
, CKA_KEY_TYPE
, CKA_VALUE_LEN
, and CKA_VALUE
attributes to the new key. Other attributes supported by the SEED key type (specifically, the flags indicating which functions the key supports) may be specified in the template for the key, or they may be assigned default initial values.
For this mechanism, the ulMinKeySize
and ulMaxKeySize
fields of the CK_MECHANISM_INFO
structure specify the supported range of SEED key sizes, in bytes, which is 16.
The algorithm block size is 16 bytes.
