Passing the login hint for identity info

This is an OIDC standard of passing the User Identity information from Portal to Identity provider (HSID). Portal will initiate an OIDC authorization call to Aikyam with the login_hint parameter. This parameter will be used to identify the user, and the step-up process will be initiated.

• The login_hint parameter will be used to pass JWE token with “hnt” as “idspec” in a JWE protected header and encrypted payload containing Big 4 along with the HSID UUID. (below sample program for more detail)
• After the OIDC, this token will be validated by HSID for authenticity and Big 4 will be extracted to perform further processing.
