NAME
Crypt::Passphrase::HSM - A hasher using hardware for Crypt::Passphrase
SYNOPSIS
my $passphrase = Crypt::Passphrase->new(
encoder => {
module => 'HSM',
provider => '/usr/lib/pkcs11/some-pkcs11.so',
active => '3',
},
);
DESCRIPTION
This module wraps hashes the password using an hmac. By using identifiers for the peppers, it allows for easy rotation of peppers. Unlike traditional mechanisms it relies fully depends on the secrecy of the peppers in the HSM instead of computational difficulty, as such the key size should probably equal the output size.
METHODS
new(%args)
This creates a new encoder. It takes the following named arguments:
provider
The path to the PKCS11 provider. This is mandatory.
slot
The slot used on the provider, this defaults to the first listed slot.
active
This is the identifier of the active pepper. This is mandatory.
prefix
The prefix that is used when looking up keys in the HSM. It defaults to
'pepper-'
.pin
The PIN that is used for logging in, if any.
user_type
The type of user you're logging in with. This defaults to 'user', and you're unlikely to want to change that.
algorithm
This is the algorithm that's used for hashing. It supports any mechanism on your HSM that can sign and verify, common values are
'sha1-hmac'
,'sha224-hmac'
,'sha256-hmac'
,'sha384-hmac'
, and'sha512-hmac'
(the default).
hash_password($password)
This hashes the $password
in the HSM using the given algorithm.
verify_password($password, $hash)
Verify a password with the HSM.
needs_rehash($hash)
This will check if the hash needs a rehash.
crypt_subtypes
This returns the supported algorithms.
