Crypt::Perl::ECDSA::PublicKey - object representation of ECDSA public key
#Use Parse.pm or a private key’s get_public_key() #rather #than instantiating this class directly. #This works even if the object came from a key file that doesn’t #contain the curve name. $pbkey->get_curve_name(); if ($payload > ($pbkey->max_sign_bits() / 8)) { die "Payload too long!"; } $pbkey->verify($payload, $sig) or die "Invalid signature!"; #For JSON Web Algorithms (JWT et al.), cf. RFC 7518 page 8 #This verifies against the appropriate SHA digest rather than #against the original message. $pbkey->verify_jwa($payload, $sig) or die "Invalid signature!"; #---------------------------------------------------------------------- #Includes “kty”, “crv”, “x”, and “y”. #Add in whatever else your application needs afterward. # #This will die() if you try to run it with a curve that #doesn’t have a known JWK “crv” value. # my $pub_jwk = $pbkey->get_struct_for_public_jwk(); #Useful for JWTs my $jwt_alg = $pbkey->get_jwa_alg();
