Moodle. LTI Advantage Automatic Registration

Question

I'm trying to implement automatic Tool registration in Moodle. As described here: https://moodlelti.theedtech.dev/dynreg/

Registration is successful and in the settings, I get the following result:

But I am not satisfied with the "Public type key" field.

I want the "Public key type" field to be set as RSA key and the Public key field to be filled in after automatic registration.

I can't find the JSON structure that should be passed for this setting. So how and what parameters should I pass to set the key fields the way I want?

Answer 1

I'd suggest reading the specification, specifically the part about the tool's openid-configuration, and even more specifically about the jwks_uri property: https://www.imsglobal.org/spec/lti-dr/v1p0#openid-configuration-0

This section clearly states:

"This specification requires the tool to expose its public key using a JSON Web Key Set URI."
