jose-fmt - Converts JSON between serialization formats

       Nathaniel McCallum npmccallum@redhat.comJOSE-FMT(1)

       Extract the alg parameter from a JWE Protected Header:

           $ jose fmt -j "$jwe" -Og protected -yOg alg -Su-
           A128KW

       List all JWKs in a JWKSet (one per line):

           $ echo "$jwkset" | jose fmt -j- -Og keys -Af-
           {"kty":"oct",...}
           {"kty":"EC",...}

       Change the algorithm in a JWK:

           $ echo "$jwk" | jose fmt -j- -j '"A128GCM"' -s alg -Uo-
           {"kty":"oct","alg":"A128GCM",...}

       Build a JWE template:

           $ jose fmt -j '{}' -cs unprotected -q A128KW -s alg -UUo-
           {"unprotected":{"alg":"A128KW"}}

       This josefmt command provides a mechanism for building and parsing JSON objects from the command line.
       It operates as a simple stack machine. All commands operate on the TOP item of the stack and,
       occasionally, the PREV item of the stack. Commands that require a specific type of value will indicate it
       in parentheses. For example: "TOP (arr.)".

       This program returns 0 on success or the index of the option which failed.
