This class exposes functions for LTI 1.3 Key Management.| get_private_key() X-Ref |
| Returns the private key to use to sign outgoing JWT. return: array keys are kid and key in PEM format. |
| get_jwks() X-Ref |
| Returns the JWK Key Set for this site. return: array keyset exposting the site public key. |
| fix_jwks_alg(array $jwks, string $jwt) X-Ref |
| Take an array of JWKS keys and infer the 'alg' property for a single key, if missing, based on an input JWT. This only sets the 'alg' property for a single key when all the following conditions are met: - The key's 'kid' matches the 'kid' provided in the JWT's header. - The key's 'alg' is missing. - The JWT's header 'alg' matches the algorithm family of the key (the key's kty). - The JWT's header 'alg' matches one of the approved LTI asymmetric algorithms. Keys not matching the above are left unchanged. return: array the fixed keyset array. param: array $jwks the keyset array. param: string $jwt the JWT string. |
