Load EC Public Key from X,Y Values (easier)

See more ECC Examples

Demonstrates how to load an ECDSA public key from X and Y values using the LoadEcdsa method introduced in Chilkat v9.5.0.85. Perl

use chilkat();

$success = 0;

# Note: This example requires Chilkat v9.5.0.85 or greater.

# We have the following x and y values in hex (for an EC point on the P-256 curve).
$x = "1ccbe91c075fc7f4f033bfa248db8fccd3565de94bbfb12f3c59ff46c271bf83";
$y = "ce4014c68811f9a21a1fdb2c0e6113e06db7ca93b7404e78dc7ccd5ca89a4ca9";

$pubkey = chilkat::CkPublicKey->new();
$success = $pubkey->LoadEcdsa("secp256r1",$x,$y);
if ($success == 0) {
    print $pubkey->lastErrorText() . "\r\n";
    exit;
}

print "Success." . "\r\n";
