Chilkat2-Python

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.

# (optional)  Set the "not process before" timestamp to now.

# (optional)  Set the timestamp defining an expiration time (end time) for the token
# to be now + 1 hour (3600 seconds)
success = claims.AddIntAt(-1,"exp",curDateTime + 3600)

# Produce the smallest possible JWT:

# Create the JWT token.
token = jwt.CreateJwtPk(jose.Emit(),claims.Emit(),privKey)
