NAME

Crypt::Keyczar::Verifier - Verify data usign sets of symmetric or asymmetric keys.

SYNOPSIS

use Crypt::Keyczar::Verifier;

my $verifier = Crypt::Keyczar::Verifier->new('/path/to/keyset');
$verifier->verify($message, $signature) ? 'OK' : 'NG';

DESCRIPTION

Crypt::Keyczar::Verifier are used strictly to verify signatures. Typically, Verifiers will read sets of public keys, although may also be instantiated with sets of symmetric or private keys.

METHOD

* new($keyset_path)

Create a new Crypt::Keyczar::Verifier object with a file-based key set location. This will attempt to read the keys using a Crypt::Keyczar::FileReader. The corresponding key set must have a purpose of either 'VERIFY' or 'SIGN_AND_VERIFY'.

* new($reader_object)

Create a new Crypt::Keyczar::Verifier object with a Crypt::Keyczar::Reader object.

* verify($message, $signature)

Verifies a $sigunature on the given $message.
