Encrypt produces encrypted JWT token given arbitrary binary payload key management and encryption algorithms to use ( see constants for list of supported algs ) and management key . Management key is of different type for different key management alg see specific key management alg implementation documentation . It returns 5 parts encrypted JWT token as string and not nil error if something went wrong .
