json-web-key-generator

A commandline Java-based generator for JSON Web Keys (JWK) and JSON Private/Shared Keys (JPSKs).

Standalone run

To compile, run mvn package. This will generate a json-web-key-generator-0.9-SNAPSHOT-jar-with-dependencies.jar in the /target directory.

To generate a key, run java -jar target/json-web-key-generator-0.9-SNAPSHOT-jar-with-dependencies.jar -t <keytype>. Several other arguments are defined which may be required depending on your key type:

usage: java -jar json-web-key-generator.jar -t <keyType> [options]
 -t,--type <arg>           Key Type, one of: RSA, oct, EC, OKP
 -s,--size <arg>           Key Size in bits, required for RSA and oct key
                           types. Must be an integer divisible by 8
 -c,--curve <arg>          Key Curve, required for EC or OKP key type.
                           Must be one of P-256, secp256k1, P-384, P-521
                           for EC keys or one of Ed25519, Ed448, X25519,
                           X448 for OKP keys.
 -u,--usage <arg>          Usage, one of: enc, sig (optional)
 -a,--algorithm <arg>      Algorithm (optional)
 -i,--id <arg>             Key ID (optional), one will be generated if not
                           defined
 -g,--idGenerator <arg>    Key ID generation method (optional). Can be one
                           of: date, timestamp, sha256, sha1, none. If
                           omitted, generator method defaults to
                           'timestamp'.
 -I,--noGenerateId         <deprecated> Don't generate a Key ID.
                           (Deprecated, use '-g none' instead.)
 -p,--showPubKey           Display public key separately (if applicable)
 -S,--keySet               Wrap the generated key in a KeySet
 -o,--output <arg>         Write output to file. Will append to existing
                           KeySet if -S is used. Key material will not be
                           displayed to console.
 -P,--pubKeyOutput <arg>   Write public key to separate file. Will append
                           to existing KeySet if -S is used. Key material
                           will not be displayed to console. '-o/--output'
                           must be declared as well.
 -x,--x509                 Display keys in X509 PEM format

Docker

Build with docker

Example:

# Optional TAG
#TAG="your/tag:here"
# Example: TAG="<your_docker_id>/json-web-key-generator:latest"
$ docker build -t $TAG .

If building from git tags then run the following to store the tag, and the commit in the docker image label.

TAG=$(git describe --abbrev=0 --tags)
REV=$(git log -1 --format=%h)
docker build -t <your_docker_id>/json-web-key-generator:$TAG --build-arg GIT_COMMIT=$REV --build-arg GIT_TAG=$TAG .
docker push <your_docker_id>/json-web-key-generator:$TAG

# or push all the tags
docker push <your_docker_id>/json-web-key-generator --all-tags

Run from docker

Example of running the app within a docker container to generate a 2048 bit RSA JWK.

$ docker run --rm <your_docker_id>/json-web-key-generator:latest -t RSA -s 2048
