  • Some providers also display a Keyset URL or a Public JWK URL that looks similar to this: https://www.providerdomain/lti/jwks In this case, this URL can also be used INSTEAD of the public key. 

• Tool JWKS URL
  The Tool JWKS URL is provided by the LTI tool provider and must be entered in this field, e.g., https://www.providerdomain/lti/jwks.  

• Client ID
  Should be used when registering to the LTI tool  

It is only necessary to define a public key OR the Tool JWKS URL (sometimes called Keyset URL by the LTI provider). 

Note: Please consider that a license is needed to use LTI 1.3. Furthermore, the new architecture is needed because of the changed authentication.
