The Galois/Counter Mode (GCM) is a typical block cipher modes of operation using block cipher algorithm. In this version, we provide Advanced Encryption Standard (AES) processing ability, the cipherkey length for AES should be 128/192/256 bits. Our implementation takes a fix-sized (128 bits per block) payload and additional authenticated data (AAD) streams, but text may have a variety of length in different situation. Thus, you need to provide the length in bits accompany with the data or the AAD. Meanwhile, the ciphers which is the output of the primitive also comply to this pattern.
