WHAT IS ARGON2?

Argon2 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. 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.

FREQUENTLY ASKED QUESTIONS


WHAT IS PASSWORD HASHING?

Password hashing is a one-way process of securing plain text password by
creating a bit string of a fixed size called hash using cryptographic hash
function. Cryptographic hash functions designed to be a one-way function, that
is, a function which is infeasible to invert.


WHAT IS PASSWORD HASHING COMPETITION?

Password Hashing Competition, organized by cryptography and security experts, is
an open competition to raise awareness of the need of strong password hashing
algorithms and to identify hash functions that can be recognized as a
recommended standard. Argon2 was selected as the final PHC winner on 20 July
2015.

NOTES

Note #1: We do not store any passwords, never.

Note #2: Always choose a strong password, containing special characters,
lowercase and uppercase letters and numbers.

Note #3: Always use trusted libraries for creating password hashes.

Note #4: Stop using weak hashing algorithms such as md5, sha1, sha256, etc.
