NAME

Crypt::Passphrase::Argon2::AES - A peppered AES-encrypted Argon2 encoder for Crypt::Passphrase

SYNOPSIS

my $passphrase = Crypt::Passphrase->new(
    encoder => {
        module  => 'Argon2::AES',
        peppers => {
            1 => pack('H*', '0123456789ABCDEF...'),
            2 => pack('H*', 'FEDCBA9876543210...'),
        },
    },
);

DESCRIPTION

This class implements peppering by encrypting the hash using AES (unlike Crypt::Passphrase::Pepper::Simple which hashes the input instead).

METHODS

new

This constructor takes all arguments also taken by Crypt::Passphrase::Argon2, with the following additions:

• peppers

  This is a map of identifier to pepper value. The identifiers should be (probably small) numbers, the values should be random binary strings that must be either 16, 24 or 32 bytes long.

• active

  This is the identifier of the active pepper. By default it will be the identifier with the highest (numerical) value.

• mode

  This is the mode that will be used with AES. Values values are 'ecb', 'cbc' (the default), 'cfb', 'ofb' and 'ctr'.
