To brief on the requirement, environment set up dual mode of authentication, one is via API ID - API Key and second is JWT.

For JWT, they have specific requirement like below

  1. need to use ES256 Algorithm
  2. An Eliptical curve P-256 Key set to be used for JWK
  3. Expiry time should be 180s
  4. Data (in payload) to be hashed with SHA-256.

We are using shell script and openssl to achieve above requirement. We are converting Payload and Header into base64url encoding and generating a signature which is also encoded to base64url.

Using curl command we are trying to POST the above generated JWT along with API-ID and API Key to the target system
