Hi Pablo,

Tried the test vector zuc256_test_case_auth_1 and the digest did not match with the generated digest in our platform.

As per spec, IV[i] for i = 17 to 24 are 6-bit string occupying the 6 least signi cant bits of a byte.
But in the vectors, The values in the IV(byte -17 to 24) are > 0x3f.

Could you please elaborate how these bytes are considered for generation of digest.

Regards
Sagar

Fix the IV and MAC in the test vectors added for zuc 256-bit key

Fixes: fa5bf9345d4e (test/crypto: add ZUC cases with 256-bit keys)

The new vectors are failing for us. Could you check if the ones we added work for you?

Thanks,
Pablo
