The jose-util command line utility allows for encryption, decryption, signing
and verification of JOSE messages. Its main purpose is to facilitate dealing
with JOSE messages when testing or debugging.
The utility includes the subcommands encrypt, decrypt, sign, verify and
expand. Examples for each command can be found below.
Algorithms are selected via the --alg and --enc flags, which influence the
alg and enc headers in respectively. For JWE, --alg specifies the key
management algorithm (e.g. RSA-OAEP) and --enc specifies the content
encryption algorithm (e.g. A128GCM). For JWS, --alg specifies the
signature algorithm (e.g. PS256).
Input and output files can be specified via the --in and --out flags.
Either flag can be omitted, in which case jose-util uses stdin/stdout for
input/output respectively. By default, each command will output a compact
message, but it's possible to get the full serialization by supplying the
--full flag.
Keys are specified via the --key flag. Supported key types are naked RSA/EC
keys and X.509 certificates with embedded RSA/EC keys. Keys must be in PEM
or DER formats.
cram is used for testing. This can be installed with pip or sudo apt install python-cram See the travis file for how this is used in testing. For example,
go build && PATH=$PWD:$PATH cram -v jose-util.t
Takes a plaintext as input, encrypts, and prints the encrypted message.
echo 'test message' | jose-util encrypt --key public-key.pem --alg RSA-OAEP --enc A128GCM
Takes an encrypted message (JWE) as input, decrypts, and prints the plaintext.
jose-util decrypt --key private-key.pem
Takes a payload as input, signs it, and prints the signed message with the embedded payload.
jose-util sign --key private-key.pem --alg PS256
Reads a signed message (JWS), verifies it, and extracts the payload.
jose-util verify --key public-key.pem
Expands a compact message to the full serialization format.
jose-util expand --format JWE # Expands a compact JWE to full format
jose-util expand --format JWS # Expands a compact JWS to full format
