See more Ed25519 Examples

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

Note: This example requires Chilkat v9.5.0.83 or greater.

//  See Global Unlock Sample for sample code.

//  Generates a new eddsa key and stores it in privKey.

//  Examine the ed25519 key in JWK format;
cJwk := oPrivKey:GetJwk()

oJson := CreateObject("Chilkat.JsonObject")

? oJson:Emit()

//  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.
