What is Argon2?
Argon2 is cryptographic hashing algorithm, most recommended for password hashing. Argon2 has 3 variants: Argon2d, Argon2i and Argon2id. Argon2i is optimized for password hashing. Argon2 has 6 input parameters: password, salt, memory cost (the memory usage of the algorithm), time cost (the execution time of the algorithm and the number of iterations), parallelism factor (the number of parallel threads), hash length.Learn more »
