<!--- Provide a general summary of the issue in the Title above --> ## Detailed Description 1. parsePassport → return Passport object from content of Passport JWT (string) 2. validatePassport (vs public key) → requires passportBroker config (to fetch public key) 3. can we cache public keys for a period of time? (like a day) → dont need to constantly fetch them 4. getVisas → return list of visa JWTs 5. getPermissionsForPassport → return list of permissions from passport (compiled list of all permissions from all visas, remove duplicates) ## Possible Implementation <!--- Not obligatory, but suggest an idea for implementing addition or change --> <!--- or provide an example feature somewhere else that you would like to see -->
