NAME

Crypt::Passphrase::Argon2::HSM - HSM encrypted Argon2 hashes for Crypt::Passphrase

SYNOPSIS

 my $passphrase = Crypt::Passphrase->new(
     encoder => {
         module   => 'Argon2::HSM',
         provider => '/usr/lib/pkcs11/some-pkcs11.so',
         active   => '3',
     },
 );

DESCRIPTION

This class implements peppering by encrypting the hash using HSM. Note that it does not do the argon2 computation in the HSM.

METHODS

new

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

• provider

  The path to the PKCS11 provider. This is mandatory.

• slot

  The slot used on the provider, this defaults to the first listed slot.

• active

  This is the identifier of the active pepper. This is mandatory.

• prefix

  The prefix that is used when looking up keys in the HSM. It defaults to 'pepper-'.

• pin

  The PIN that is used for logging in, if any.

• user_type

  The type of user you're logging in with. This defaults to 'user', and you're unlikely to want to change that.

• cipher

  This is the cipher that's used for peppering. This can be any mechanism supporting encrypt/decrypt. The default is 'aes-cbc'.
