(Perl) 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.

# Load an Ed25519 (EdDSA) private key from a PEM file.

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

$success = $jose->AppendString("alg","EdDSA");

# Now build the JWT claims (also known as the payload)
$claims = chilkat::CkJsonObject->new();
$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.
$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->put_AutoCompact(1);

# Create the JWT token.
$token = $jwt->createJwtPk($jose->emit(),$claims->emit(),$privKey);

print $token . "\r\n";
