Hello.

I use OpenSSL for my work and particularly the AES 256 algorithm with the GCM mode.

When I test this mode, the ciphered text is correct but the authentication tag is not correct.

I think my test vectors are correct (source : NIST and my cipher room).

Could you help me? If yes, how can we proceed?
