       jose-jwk-use - Validates a key for the specified use(s)


       jose jwk use -i JWK [-a] [-r] -u OP


       The  jose jwk use command validates one or more JWK(Set) inputs for a given set of usages.
       This will be validated against the "use" and "key_ops" properties of each JWK.

       By default, if a JWK has no  restrictions  an  operation  will  be  allowed.  However,  by
       specifying  the  -r  option  you  can  ensure  that  a  JWK  will not be allowed unless it
       explicitly permits the option.

       In normal operation, jose jwk use will fail if any of the JWKs do not  validate.  However,
       if  the -o option is used jose jwk use will instead write a JWK(Set) containing all of the
       input keys that validate. If no JWKs validate, the command will fail.


       -i JSON, --input=JSON
              Parse JWK(Set) from JSON

       -i FILE, --input=FILE
              Read JWK(Set) from FILE

       -i -, --input=-
              Read JWK(Set) standard input

       -u sign, --use=sign
              Validate the key for signing

       -u verify, --use=verify
              Validate the key for verifying

       -u encrypt, --use=encrypt
              Validate the key for encrypting

       -u decrypt, --use=decrypt
              Validate the key for decrypting

       -u wrapKey, --use=wrapKey
              Validate the key for wrapping

       -u unwrapKey, --use=unwrapKey
              Validate the key for unwrapping

       -u deriveKey, --use=deriveKey
              Validate the key for deriving keys

       -u deriveBits, --use=deriveBits
              Validate the key for deriving bits

       -a, --all
              Succeeds only if all operations are allowed

       -r, --required
              Operations must be explicitly allowed

       -o FILE, --output=FILE
              Filter keys to FILE as JWK(Set)

       -o -, --output=-
              Filter keys to standard output as JWK(Set)

       -s, --set
              Always output a JWKSet


       Examples of both success and failure from a private and public key:

           $ jose jwk gen -i ´{"alg":"ES256"}´ -o prv.jwk
           $ jose jwk pub -i prv.jwk -o pub.jwk
           $ jose jwk use -i prv.jwk -u sign
           $ echo $?
           $ jose jwk use -i pub.jwk -u sign
           $ echo $?
