Topic: wc_AesGcmEncrypt/Decrypt nonce/iv size
What are the effective limits of the IV size for these calls?
We intend to use a 128bit (16 byte) IV, will all of the bits be used?

Hi miennaco,
The AES GCM IV is normally 12-bytes, but it supports any length. An IV size not equal to 12-byte will first be GHASH'd then used.
See the code here:

Thanks,
