NAME

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

SYNOPSIS

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

OVERVIEW

       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.

OPTIONS

       •   -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

       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 $?
           0
           $ jose jwk use -i pub.jwk -u sign
           $ echo $?
           1
