Questions tagged [argon2-ffi]

Argon2 is a hashing algorithm, primarily for password hashing. Use with specific language tags for questions regarding implementation

Argon2 is a hashing algorithm designed for the Password Hashing Competition, which it ultimately won. From the GitHub repository

Argon2 is a password-hashing function that summarizes the state of the art in the design of memory-hard functions and can be used to hash passwords for credential storage, key derivation, or other applications.

It has a simple design aimed at the highest memory filling rate and effective use of multiple computing units, while still providing defense against tradeoff attacks (by exploiting the cache and memory organization of the recent processors).

Argon2 has been implemented in a number of programming languages. Questions should pertain to using it within those languages.
