NAME

6       jose-jws-ver - Verifies a JWS using the supplied JWKs
7

SYNOPSIS

9       jose jws ver -i JWS [-I PAY] -k JWK [-a] [-O PAY]
10

OVERVIEW

12       The jose jws ver command verifies a signature over a payload using one
13       or more JWKs. When specifying more than one JWK (-k), the program will
14       succeed when any of the provided JWKs successfully verify a signature.
15       Alternatively, if the -a option is given, the program will succeed only
16       when all JWKs successfully verify a signature.
17
18       If the JWS is a detached JWS, meaning that the payload is stored in
19       binary form external to the JWS itself, the payload can be loaded using
20       the -I parameter.
21
22       Please note that, when specifying the -O option to output the payload,
23       the payload is output whether or not the signature validates.
24       Therefore, you must check the return value of the command before
25       trusting the data.
26

OPTIONS

28       •   -i JSON, --input=JSON : Parse JWS from JSON
29
30       •   -i FILE, --input=FILE : Read JWS from FILE
31
32       •   -i -, --input=- : Read JWS from standard input
33
34       •   -I FILE, --detached=FILE : Read decoded payload from FILE
35
36       •   -I -, --detached=- : Read decoded payload from standard input
37
38       •   -k FILE, --key=FILE : Read JWK(Set) from FILE
39
40       •   -k -, --key=- : Read JWK(Set) from standard input
41
42       •   -O FILE, --detach=FILE : Decode payload to FILE
43
44       •   -O -, --detach=- : Decode payload to standard output
45
46       •   -a, --all : Ensure the JWS validates with all keys
47

EXAMPLES

49       Verify a regular JWS and output the payload:
50
51           $ jose jws ver -i msg.jws -k key.jwk -O msg.txt
52
53       Verify a detached JWS without outputting the payload:
54
55           $ jose jws ver -i msg.jws -I msg.txt -k key.jwk
56
57       Ensure that a JWS is signed with all specified keys:
58
59           $ jose jws ver -i msg.jws -k ec.jwk -k rsa.jwk -a
