Implementation of AES-GCM encryption algorithm for high

AES-GCM authenticated encryption. AES with Galois/Counter Mode (AES-GCM) provides both authenticated encryption (confidentiality and authentication) and the ability to check the integrity and authentication of additional authenticated data (AAD) that is sent in the clear. AES-GCM is specified in NIST Special Publication 800-38D . Performance costs essentially 2 x AES operations per block; Cannot be parallelized; CCM ciphers are available in OpenSSL as of TLS 1.3 (2018), but disabled by default. GCM (Galois Counter Mode) GCM ciphers are the most widely used block ciphers worldwide. Mandatory as of TLS 1.2 (2008) and used by default by most clients.

AES-GCM is a more secure cipher than AES-CBC, because AES-CBC, operates by XOR'ing (eXclusive OR) each block with the previous block and cannot be written in parallel. This affects performance due to the complex mathematics involved requiring serial encryption.

Apr 20, 2020 · TL;DR If you only have 5 seconds to pick only one, go with AES-GCM. Most systems/libraries do both AES-GCM and ChaCha20-Poly1305 out-of-the-box. AES-GCM (Galois Counter Mode) The most widely used b…
