NAME

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

SYNOPSIS

           require Net::DNS::SEC::ECDSA;

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

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

DESCRIPTION

       Implementation of ECDSA elliptic curve digital signature generation and verification
       procedures.

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

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

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

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