NAME

       jose-jws-ver - Verifies a JWS using the supplied JWKs

SYNOPSIS

       jose jws ver -i JWS [-I PAY] -k JWK [-a] [-O PAY]

OVERVIEW

       The jose jws ver command verifies a signature over a payload using one or more JWKs. When
       specifying more than one JWK (-k), the program will succeed when any of the provided JWKs
       successfully verify a signature. Alternatively, if the -a option is given, the program
       will succeed only when all JWKs successfully verify a signature.

       If the JWS is a detached JWS, meaning that the payload is stored in binary form external
       to the JWS itself, the payload can be loaded using the -I parameter.

       Please note that, when specifying the -O option to output the payload, the payload is
       output whether or not the signature validates. Therefore, you must check the return value
       of the command before trusting the data.

OPTIONS

       •   -i JSON, --input=JSON : Parse JWS from JSON

       •   -i FILE, --input=FILE : Read JWS from FILE

       •   -i -, --input=- : Read JWS from standard input

       •   -I FILE, --detached=FILE : Read decoded payload from FILE

       •   -I -, --detached=- : Read decoded payload from standard input

       •   -k FILE, --key=FILE : Read JWK(Set) from FILE

       •   -k -, --key=- : Read JWK(Set) from standard input

       •   -O FILE, --detach=FILE : Decode payload to FILE

       •   -O -, --detach=- : Decode payload to standard output

       •   -a, --all : Ensure the JWS validates with all keys

EXAMPLES

       Verify a regular JWS and output the payload:

           $ jose jws ver -i msg.jws -k key.jwk -O msg.txt

       Verify a detached JWS without outputting the payload:

           $ jose jws ver -i msg.jws -I msg.txt -k key.jwk

       Ensure that a JWS is signed with all specified keys:

           $ jose jws ver -i msg.jws -k ec.jwk -k rsa.jwk -a
