VERSION

 $Revision: 1.009 $
 $Date: Tue Oct 16 23:22:27 PDT 2018 $

SYNOPSIS

Elliptic Curve Digital Signature Algorithm (ECDSA)

    use Crypt::EC_DSA;

    my $ecdsa = new Crypt::EC_DSA;

    my ($pubkey, $seckey) = $ecdsa->keygen;

    my $msg = 'Hello, world!';

    my $signature = $ecdsa->sign( Message => $msg, Key => $seckey );

    print "Verified\n" if $ecdsa->verify( Message => $msg, Key => $pubkey,
                                          Signature => $signature );

METHODS

new

Creates and returns a new Crypt::EC_DSA object. The following optional named parameters can be provided:

    Curve - The name of the elliptic curve to use. Defaults to 'secp256k1'. To use an unnamed curve, set the curve using the curve accessor.

    Debug - Set to a true value to have the module emit messages useful for debugging.

keygen

Generates and returns an ECDSA key-pair as a two-element list, with the public key as the first element and the secret key as the second.

sign

Generates and returns an ECDSA signature. The following named parameters are required:

    Key - The private key of the signer

    Message - The message to be signed

verify

Verify a signature. Returns a true value if the verification succeeds and false otherwise. The following named parameters are required:

    Key - The public key of the signer

    Signature - The signature

    Message - The message that was signed

ACCESSORS

Accessors can be called with no arguments to query the value of an object property, or with a single argument, to set the property to a specific value (unless it is read-only).

debug

Set true to emit helpful messages for debugging purposes, false otherwise. Default is false.

curve

The elliptic curve to use (a Math::EllipticCurve::Prime object).
