WebNov 6, 2024 · Galois/Counter mode is an AEAD mode of encryption. It combines Counter mode encryption with an authentication mechanism. And, it protects both plaintext and additional authenticated data (AAD). ... As GCM uses AES for encryption, the IV or the counter is 16 bytes. Therefore, we use the first 12 bytes as the IV and the last 4 bytes … WebWhen using an authenticated encryption mode (GCM, CCM, OCB, and chacha20-poly1305 are currently supported), the cipher.setAAD() method sets the value used for the …
