Create JWT Using Ed25519 Private Key (EdDSA)

See more JSON Web Token (JWT) Examples

Demonstrates how to create a JWT using an Ed25519 private key. If the private key is Ed25519, which is an EdDSA algorithm, the JOSE header's "alg" member should be set to "EdDSA".

Note: This example requires Chilkat v9.5.0.95 or greater.
