Crypt::OpenSSL::ECDSA(User Contributed Perl DocumentatCrypt::OpenSSL::ECDSA(3)

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

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
       This module provides an interface to the	ECDSA (Elliptic	Curve Digital
       Signature Algorithm) functions in OpenSSL

       Tested against OpenSSL 1.0.2

   Export
       None by default.

   Exportable constants
	   ECDSA_F_ECDSA_CHECK
	   ECDSA_F_ECDSA_DATA_NEW_METHOD
	   ECDSA_F_ECDSA_DO_SIGN
	   ECDSA_F_ECDSA_DO_VERIFY

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.
