Demonstrates how to generate a new Ed25519 public/private key pair. Chilkat2 Perl

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

my $eddsa = Chilkat2::EdDSA->new;
my $prng = Chilkat2::Prng->new;
my $privKey = Chilkat2::PrivateKey->new;

# Generates a new eddsa key and stores it in privKey.
my $success = $eddsa->GenEd25519Key($prng, $privKey);
if (!$success) {
    print $eddsa->LastErrorText, "\n";
    exit;
}

# Examine the ed25519 key in JWK format;
my $jwk = $privKey->GetJwk();

my $json = Chilkat2::JsonObject->new;
$json->Load($jwk);
$json->EmitCompact(0);
print $json->Emit(), "\n";

# Sample output:
# {
#   "kty": "OKP",
#   "crv": "Ed25519",
#   "x": "SE2Kne5xt51z1eciMH2T2ftDQp96Gl6FhY6zSQujiP0",
#   "d": "O-eRXewadF0sNyB0U9omcnt8Qg2ZmeK3WSXPYgqe570",
#   "use": "sig"
# }

# In the above JWK, x is the public key, y is the private key.
# Both are 32 bytes and are base64-url encoded.
