JWK Key Generator
The jwk-keygen
command line utility generates keypairs used for asymmetric
encryption and signing algorithms in JSON Web Key (JWK) format.
Usage
The utility requires specification of both desired algorithm (alg
) and key
usage (use
) to remind that same keypair should never be used both for
encryption and signing.
Algorithms are selected via the --alg
flag, which influence the alg
header.
For JWE (--use=enc
), --alg
specifies the key management algorithm (e.g.
RSA-OAEP
). For JWS (--use=sig
), --alg
specifies the signature algorithm
(e.g. PS256
).
Output file is determined by specified usage, algorithm and Key ID, e.g.
jwk-keygen --use=sig --alg=RS512 --kid=test
produces files
jwk_sig_RS512_test
and jwk_sig_RS512_test.pub
. Keys are sent to stdout when
no Key ID is specified: neither pre-defined nor random one.
Examples
RSA 2048
Generate RSA/2048 key for encryption and output to stdout.
jwk-keygen --use enc --alg RSA-OAEP
Custom key length
Generate RSA/4096 key for signing and store to files.
jwk-keygen --use sig --alg RS256 --bits 4096 --kid test
