It is a feature of GCM that the ciphertext (excluding the authentication
tag) is identical length to the plaintext. Therefore no padding is required.

AES GCM + padding

[Dirk Menstermann]

Hi,

I'm playing around with "EVP_aes_128_gcm". This works, but it seems that EVP_*
does not include padding. Is this expected/needed or did I miss a step?

Thanks
