Verifies a JWS using the supplied JWKs


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


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.



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
