(PHP Extension) Generate an Ed25519 Key PairDemonstrates how to generate a new Ed25519 public/private key pair. Note: This example requires Chilkat v9.5.0.83 or greater.
<?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"); // This example assumes the Chilkat API to have been previously unlocked. // See Global Unlock Sample for sample code. $eddsa = new CkEdDSA(); $prng = new CkPrng(); $privKey = new CkPrivateKey(); // Generates a new eddsa key and stores it in privKey. $success = $eddsa->GenEd25519Key($prng,$privKey); if ($success == false) { print $eddsa->lastErrorText() . "\n"; exit; } // Examine the ed25519 key in JWK format; $jwk = $privKey->getJwk(); $json = new CkJsonObject(); $json->Load($jwk); $json->put_EmitCompact(false); 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. ?> |
