Description

This function checks that a claim passed to the is_authed_jwt function is valid in the given JWT. A claim consists of a claim name (e.g. "iss") and a claim value (e.g. "company A"). Claim values can also be named lists themselves. The function recursively extracts the value for claim_name from the payload. If the claim_value is atomic, it compares the retrieved value with the claimed value. Otherwise, it applies check_claim to claim_value recursively.

Usage

check_claim(claim_name, claim_value, payload)

Arguments

claim_name	name of the claim in the JWT, e.g. "iss".
claim_value	value the claim should have to pass the test.
payload	JWT payload extracted with jose::jwt_decode_hmac.

Value

TRUE if the claim is present in the JWT, FALSE if not.
