NAME

6       Crypt::OpenSSL::ECDSA - Perl extension for OpenSSL ECDSA (Elliptic
7       Curve Digital Signature Algorithm)
8

SYNOPSIS

10           use Crypt::OpenSSL::ECDSA;
11           $sig = Crypt::OpenSSL::ECDSA::ECDSA_do_sign( $digest, $eckey );
12           $r = $sig->get_r;
13           $s = $sig->get_s;
14
15           $sig = Crypt::OpenSSL::ECDSA::ECDSA_SIG->new();
16           $sig->set_r($r);
17           $sig->set_s($s);
18           Crypt::OpenSSL::ECDSA::ECDSA_do_verify( $digest, $sig, $eckey );

DESCRIPTION

21       This module provides an interface to the ECDSA (Elliptic Curve Digital
22       Signature Algorithm) functions in OpenSSL
23
24       Tested against OpenSSL 1.0.2

CLASS METHODS

45       new
46               $sig = Crypt::OpenSSL::ECDSA::ECDSA_SIG->new();
47
48           Create a new ECDSA Signature Object.
49
50           The internal "r" and "s" components are undefined.
51

OBJECT METHODS

53       get_r;
54               $r = $sig->get_r;
55
56           Gets signature "r" component.
57
58           The method returns a string representing a binary integer in
59           network (big-endian) byte order.
60
61       get_s;
62               $s = $sig->get_s;
63
64           Gets signature "s" component.
65
66           The method returns a string representing a binary integer in
67           network (big-endian) byte order.
68
69       set_r;
70               $sig->set_r($r);
71
72           Sets signature "r" component.
73
74           The argument is a string representing a binary integer in network
75           (big-endian) byte order.
76
77       set_s;
78               $sig->set_r($s);
79
80           Sets signature "s" component.
81
82           The argument is a string representing a binary integer in network
83           (big-endian) byte order.
