AES-GCM
AES run in a mode that encrypts data and detects tampering in a single step.
AES-GCM uses AES in Galois/Counter Mode, which turns the block cipher into a stream and computes an authentication tag over the ciphertext. It is a standard AEAD construction: fast, parallelizable, and it rejects any altered ciphertext instead of decrypting it. Reusing a nonce with the same key breaks its security, so nonce handling matters.
