CKM_RSA_PKCS_OAEP
The RSA PKCS OAEP mechanism can now use a supplied hashing mechanism. Previously RSA OAEP would always use SHA1 and returned an error if another was attempted.
With current firmware, PKCS#11 API and ckdemo now accept a new mechanism.
Allowed mechanisms are:
CKM_SHA1
CKM_SHA224
CKM_SHA256
CKM_SHA384
CKM_SHA512
0 (use the firmware's default engine, which is currently SHA1)
In ckdemo menu option 98 has a new value 17 - OAEP Hash Params, which can be set to use either default (CKM_SHA1) or selectable. When it is set to selectable the user is prompted for a hash mechanism when using the OAEP mechanism.
