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

loEddsa = createobject("CkEdDSA")
loPrng = createobject("CkPrng")
loPrivKey = createobject("CkPrivateKey")

// Generates a new eddsa key and stores it in privKey.
llSuccess = loEddsa.GenEd25519Key(loPrng,loPrivKey)
if (llSuccess = .F.) then
    ? loEddsa.LastErrorText
    release loEddsa
    release loPrng
    release loPrivKey
    return
endif

// Examine the ed25519 key in JWK format;
lcJwk = loPrivKey.GetJwk()

loJson = createobject("CkJsonObject")
loJson.Load(lcJwk)
loJson.EmitCompact = .F.
? loJson.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.
