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

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

import sys
import chilkat2

success = False

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

eddsa = chilkat2.EdDSA()
prng = chilkat2.Prng()
privKey = chilkat2.PrivateKey()

# Generates a new eddsa key and stores it in privKey.
success = eddsa.GenEd25519Key(prng,privKey)
if (success == False):
    print(eddsa.LastErrorText)
    sys.exit()

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

json = chilkat2.JsonObject()
json.Load(jwk)
json.EmitCompact = False
print(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.
