NAME

       Net::DNS::SEC::RSA - DNSSEC RSA digital signature algorithm

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.
