AES-CCM enforce max length

Open solney opened this issue 2 years ago • 2 comments

NIST Special Publication 800-38C Appendix 1 states that the maximum length of payload is determined by the value of q (which in turn is related to the length of the nonce).

It seems as if this condition wasn't previously enforced which could lead to the block b0 exceeding 16 bytes.

Fixed now, need bytearray instead of bytes in new test

Thanks, but this was fixed in a more generic way in v3.22
