Argon2 is a password-hashing function that can be used to hash passwords for credential storage, key derivation, or other applications.

There are two main versions of Argon2: Argon2i and Argon2d. Argon2i is the safest against side-channel attacks, while Argon2d provides the highest resistance against GPU cracking attacks.

Argon2i and Argon2d are parametrized by: * A time cost, which defines the amount of computation realized and therefore the execution time, given in number of iterations * A memory cost, which defines the memory usage, given in kibibytes * A parallelism degree, which defines the number of parallel threads

This package contains the argon2 tool for hashing data on the command-line.
