.TH ARGON2 "1" "April 2016" "argon2 " "User Commands"

.SH NAME
argon2 \- generate argon2 hashes

.SH SYNOPSIS
.B argon2 salt
.RB [ OPTIONS ]

.SH DESCRIPTION
Generate Argon2 hashes from the command line.

The supplied salt (the first argument to the command) must be at least
8 octets in length, and the password is supplied on standard input.

By default, this uses Argon2i variant (where memory access is
independent of secret data) which is the preferred one for password
hashing and password-based key derivation.
