Expn64v2gcm Work -

EXPn64v2GCM is a cryptographic mode of operation for block ciphers, specifically designed to provide both confidentiality and authenticity of data. The "EXPn" in EXPn64v2GCM stands for "Exponential," referring to the use of exponential functions in the encryption process. "64" denotes the block size of 64 bits, and "v2" indicates that it's the second version of the EXPn64GCM. "GCM" stands for Galois/Counter Mode, which is an authenticated encryption mode that provides both confidentiality and integrity.
