SYNOPSIS

require Net::DNS::SEC::RSA;
$signature = Net::DNS::SEC::RSA->sign( $sigdata, $private );
$validated = Net::DNS::SEC::RSA->verify( $sigdata, $keyrr, $sigbin );

DESCRIPTION

Implementation of RSA digital signature generation and verification procedures.

sign

    $signature = Net::DNS::SEC::RSA->sign( $sigdata, $private );

Generates the wire-format binary signature from the binary sigdata and the appropriate private key object.

verify

    $validated = Net::DNS::SEC::RSA->verify( $sigdata, $keyrr, $sigbin );

Verifies the signature over the binary sigdata using the specified public key resource record.

ACKNOWLEDGMENT

Andy Vaskys (Network Associates Laboratories) supplied the code for handling RSA with SHA1 (Algorithm 5).

The Crypt::OpenSSL::RSA package was created by Ian Robertson.
