(PHP Extension) Load EC Public Key from X,Y Values (easier)
Demonstrates how to load an ECDSA public key from X and Y values using the LoadEcdsa method introduced in Chilkat v9.5.0.85.
<?php
// The version number (9_5_0) should match version of the Chilkat extension used, omitting the micro-version number.
// For example, if using Chilkat v9.5.0.48, then include as shown here:
include("chilkat_9_5_0.php");
// 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 = new CkPublicKey();
$success = $pubkey->LoadEcdsa('secp256r1',$x,$y);
if ($success == false) {
print $pubkey->lastErrorText() . "\n";
exit;
}
print 'Success.' . "\n";
?>
