WebbThe above code first derives a "raw hash" (256-bit key), which is argon2-based key derivation, just like with scrypt.It also derives a "argon2 hash", which holds the algorithm parameters, along with random salt and derived key.The later is used for password storing and verification. Finally, the calculated hashes are tested agains a correct and wrong … WebbArgon2 is cryptographic hashing algorithm, most recommended for password hashing. It is designed by Alex Biryukov, Daniel Dinu, and Dmitry Khovratovich from University of Luxembourg. Argon2 has 3 variants: Argon2d, Argon2i and Argon2id. Argon2i is optimized for password hashing.
