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

Dim eddsa As New Chilkat.EdDSA
Dim prng As New Chilkat.Prng
Dim privKey As New Chilkat.PrivateKey

' Generates a new eddsa key and stores it in privKey.
Dim success As Boolean = eddsa.GenEd25519Key(prng,privKey)
If (success = False) Then
    Debug.WriteLine(eddsa.LastErrorText)
    Exit Sub
End If


' Examine the ed25519 key in JWK format;
Dim jwk As String = privKey.GetJwk()

Dim json As New Chilkat.JsonObject
json.Load(jwk)
json.EmitCompact = False
Debug.WriteLine(json.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.
