Hello.
I send my request to this other E-mail address because I had no response to my question with the E-mail address openssl-us...@openssl.org<mailto:openssl-us...@openssl.org>.

Objet : Problem with AES 256 algorithm / GCM mode.

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?
