With output set to json, the structure returned includes:

algorithm - the signing algorithm used.

claims- the JSON used in the JWT with the timing variables set as used

claims_b64 - the claims section of the JWT in base64 encoding

claims_str - the claims section as a string, as used in the JWT

headers - the JWT headers in JSON

headers_b64 - the headers section of the JWT in base64 encoding

headers_str - the headers section as a string, as used in the JWT

jwt - the fully signed JWT

signature_b64 - the signature section of the JWT, in base64 encoding

Note, using the JSON output allows you to build, for example, a JSON Web Signature (JWS) value by extracting the claims_64 and signature_64values to use in an X-JWS-Signature header, and then using the exactly claims body (claims_str) as the subsequent API body.
