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

$eddsa = New-Object Chilkat.EdDSA
$prng = New-Object Chilkat.Prng
$privKey = New-Object Chilkat.PrivateKey

# Generates a new eddsa key and stores it in privKey.
$success = $eddsa.GenEd25519Key($prng,$privKey)
if ($success -eq $false) {
    $($eddsa.LastErrorText)
    exit
}

# Examine the ed25519 key in JWK format;
$jwk = $privKey.GetJwk()

$json = New-Object Chilkat.JsonObject
$json.Load($jwk)
$json.EmitCompact = $false
$($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.
