Load an Ed25519 Private Key from Hex

Demonstrates how to load an Ed25519 private key from raw hex bytes. Chilkat2 Perl

use strict;
use warnings;
use Chilkat2;

# This example assumes the Chilkat API to have been previously unlocked.
# See Global Unlock Sample for sample code.

my $privKey = Chilkat2::PrivateKey->new;

# We have the hexidecimal encoded bytes of the private key and public key:
my $privKeyHex = 'd4ee72dbf913584ad5b6d8f1f769f8ad3afe7c28cbf1d4fbe097a88f44755842';
my $pubKeyHex = '19bf44096984cdfe8541bac167dc3b96c85086aa30b6b6cb0c5c38ad703166e1';

# Load these values into the Chilkat private key object:
my $success = $privKey->LoadEd25519($privKeyHex, $pubKeyHex);
if (!$success) {
    print $privKey->LastErrorText, "\n";
    exit;
}

# ---------------------------------------------------------------
# We don't actually need the public key.  If we pass an empty string for the public key,
# Chilkat will automatically compute it.
my $privKey2 = Chilkat2::PrivateKey->new;
$success = $privKey2->LoadEd25519($privKeyHex, '');

# Let's get the public key to see that it computed the same value.
my $sbPubKeyHex = Chilkat2::StringBuilder->new;
$privKeyHex = $privKey2->GetRawHex($sbPubKeyHex);
print 'computed public key = ', $sbPubKeyHex->GetAsString(), "\n";

# The output should be:
# computed public key = 19bf44096984cdfe8541bac167dc3b96c85086aa30b6b6cb0c5c38ad703166e1
