Argon2 Definition: Argon2 is a memory-hard password hashing function and PHC winner; the Argon2id variant is the recommended default for secure password storage.
Argon2 is a memory-hard password hashing and key derivation function that won the Password Hashing Competition in 2015 and is recommended for storing passwords securely. It comes in three variants: Argon2d, which maximizes resistance to GPU cracking; Argon2i, which is hardened against side-channel attacks; and Argon2id, a hybrid that is the generally recommended default. Its tunable memory, time, and parallelism parameters make brute-force and hardware-accelerated attacks costly. Argon2 is specified in RFC 9106.
