SHA-1-PBE for CAST128-CBC (CAST5-CBC), denoted CKM_PBE_SHA1_CAST128_CBC or CKM_PBE_SHA1_CAST5_CBC, is a mechanism used for generating a CAST128 (CAST5) secret key and an IV from a password and a salt value by using the SHA-1 digest algorithm and an iteration count. This functionality is analogous to that defined in PKCS#5 PBKDF1 for MD5 and DES.
It has a parameter, a CK_PBE_PARAMS structure. The parameter specifies the input information for the key generation process and the location of the application-supplied buffer which will receive the 8-byte IV generated by the mechanism.
The length of the CAST128 (CAST5) key generated by this mechanism may be specified in the supplied template; if it is not present in the template, it defaults to 8 bytes.
