NAME

Crypt::OpenSSL::ECDSA - Perl extension for OpenSSL ECDSA (Elliptic Curve Digital Signature Algorithm)

CONTENTS

SYNOPSIS



    use Crypt::OpenSSL::ECDSA;
    $sig = Crypt::OpenSSL::ECDSA::ECDSA_do_sign( $digest, $eckey );
    $r = $sig->get_r;
    $s = $sig->get_s;

    $sig = Crypt::OpenSSL::ECDSA::ECDSA_SIG->new();
    $sig->set_r($r);
    $sig->set_s($s);
    Crypt::OpenSSL::ECDSA::ECDSA_do_verify( $digest, $sig, $eckey );



DESCRIPTION

CLASS METHODS

new


    $sig = Crypt::OpenSSL::ECDSA::ECDSA_SIG->new();



Create a new ECDSA Signature Object.

The internal r and s components are undefined.

OBJECT METHODS

get_r;


    $r = $sig->get_r;



Gets signature r component.

The method returns a string representing a binary integer in network (big-endian) byte order.

get_s;


    $s = $sig->get_s;



Gets signature s component.

The method returns a string representing a binary integer in network (big-endian) byte order.

set_r;


    $sig->set_r($r);



Sets signature r component.

The argument is a string representing a binary integer in network (big-endian) byte order.

set_s;


    $sig->set_r($s);



Sets signature s component.

The argument is a string representing a binary integer in network (big-endian) byte order.
