json-web-key-generator
A commandline Java-based generator for JSON Web Keys (JWK) and JSON Private/Shared Keys (JPSKs).
=====================
To compile, run mvn package. This will generate a json-web-key-generator-0.5-SNAPSHOT-jar-with-dependencies.jar in the /target directory.
To generate a key, run java -jar target/json-web-key-generator-0.5-SNAPSHOT-jar-with-dependencies.jar -t <keytype>. Several other arguments are defined which may be required depending on your key type:
-a <arg> Algorithm (optional)
-c <arg> Key Curve, required for EC key type. Must be one of P-256,
P-384, P-521
-i <arg> Key ID (optional), one will be generated if not defined
-I Don't generate a Key ID if none defined
-o <arg> Write output to file (will append to existing KeySet if -S is
used), No Display of Key Material
-p Display public key separately
-s <arg> Key Size in bits, required for RSA and oct key types. Must be
an integer divisible by 8
-S Wrap the generated key in a KeySet
-t <arg> Key Type, one of: RSA, oct, EC
-u <arg> Usage, one of: enc, sig (optional)
