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.

C#

bool success = false;

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

// Demonstrates how to create a JWT using an Ed25519 private key.

Chilkat.PrivateKey privKey = new Chilkat.PrivateKey();

// Load an Ed25519 (EdDSA) private key from a PEM file.
success = privKey.LoadPemFile("qa_data/eddsa/ed25519.pem");
if (success != true) {
    Debug.WriteLine(privKey.LastErrorText);
    return;
}

Chilkat.Jwt jwt = new Chilkat.Jwt();

// Build the JOSE header
Chilkat.JsonObject jose = new Chilkat.JsonObject();

// -----------------------------------------------------------------
// Note: This example requires Chilkat v9.5.0.95 or greater.
// -----------------------------------------------------------------
success = jose.AppendString("alg","EdDSA");
success = jose.AppendString("typ","JWT");

// Now build the JWT claims (also known as the payload)
Chilkat.JsonObject claims = new Chilkat.JsonObject();
success = claims.AppendString("iss","http://example.org");
success = claims.AppendString("sub","John");
success = claims.AppendString("aud","http://example.com");

// (optional) Set the timestamp of when the JWT was created to now.
int curDateTime = jwt.GenNumericDate(0);
success = claims.AddIntAt(-1,"iat",curDateTime);

// (optional)  Set the "not process before" timestamp to now.
success = claims.AddIntAt(-1,"nbf",curDateTime);

// (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:
jwt.AutoCompact = true;

// Create the JWT token.
string token = jwt.CreateJwtPk(jose.Emit(),claims.Emit(),privKey);

Debug.WriteLine(token);

// Example output:
