OpenID Connect - id_token, what they are, how they work

In this video I am explaining how OpenID Connect id_token work and how they can be used. The video concentrates more on the usage than on all details about ways for retrieving or validate them. The video should help viewers understand the value of these token for their application.

References are made to the OpenID Connect specifications (https://openid.net/connect), JSON Web Token (https://tools.ietf.org/html/rfc7519) and to my open source project Loginbuddy (https://github.com/SaschaZeGerman/log....

This is an example Java library for validating and creating JWT: https://bitbucket.org/b_c/jose4j/wiki...

The JWS specification talks more about JWT validation:
https://tools.ietf.org/html/rfc7515

Note: where the video says: 'recreate the signature' it refers to 'validate the signature'. Recreating is only possible if an algorithm such as HS256 has been used.
