Revision a5170a8249d01e4e9cf5890b49ff6623637df09b authored by erbsland-dev on 10 September 2024, 19:24:59 UTC, committed by Tomas Mraz on 13 September 2024, 08:13:16 UTC
Add Missing Error Messages for AES-OCB Tag Length Validation
Related to #8331
Addressing found issues by adding specific error messages to improve
feedback when tag length checks fail for the `EVP_CTRL_AEAD_SET_TAG`
parameter in the AES-OCB algorithm.

- Added PROV_R_INVALID_TAG_LENGTH error to indicate when the current tag
  length exceeds the maximum tag length of the algorithm.
- Added `PROV_R_INVALID_TAG_LENGTH` error to indicate when the current tag
  length in the context does not match a custom tag length provided as
  a parameter.
- Added `ERR_R_PASSED_INVALID_ARGUMENT` error to handle cases where an
  invalid pointer is passed in encryption mode.
