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'. AUTHOR Leon Timmermans COPYRIGHT AND LICENSE This software is copyright (c) 2023 by Leon Timmermans.
