Galios/Counter Mode, or GCM Mode, is a mode of operation that uses a universal hash function over a binary Galois field to provide authenticated encryption. The mode is defined in NIST's SP 800-38D, and P1619. GCM is a high performance mode which offers both pipelining and parallelization. See more Given two message inputs, aad (additional authenticated data) and confidential data (plain text data), GCM modewill provide authentication assurances over the aad and provide both confidentiality and authentication over … See more The constructors accept a block cipher parameter (which is usually AES) and an optional GCM_TablesOption parameter.
