(Perl) Verify JWT with EdDSA / Ed25519 SignatureNote: This example requires Chilkat v9.5.0.84 or greater. Demonstrates how to verify a JWT that was signed using an Ed25519 private key. This example verifies the EdDSA signature. It also does the following:
use chilkat(); # Demonstrates how to verify a JWT with an EdDSA/Ed25519 Signature # *** Requires Chilkat v9.5.0.84 or greater. # This example assumes the Chilkat API to have been previously unlocked. # See Global Unlock Sample for sample code. # Use this Ed25519 public key for verification $jsonPubKey = "{\"kty\": \"OKP\",\"alg\": \"EdDSA\",\"crv\": \"Ed25519\",\"x\": \"11qYAYKxCrfVS_7TyWQHOg7hcvPapiMlrwIaaPcHURo\"}"; $pubKey = chilkat::CkPublicKey->new(); $success = $pubKey->LoadFromString($jsonPubKey); if ($success == 0) { print $pubKey->lastErrorText() .

"\r\n"; # Recover the original data (the payload). $payload = $jwt->getPayload($token); print $payload .
