JOSE CLI
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.
Usage
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
managment 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.
Examples
Encrypt
Takes a plaintext as input, encrypts, and prints the encrypted message.
jose-util encrypt -k public-key.pem --alg RSA-OAEP --enc A128GCM
Decrypt
Takes an encrypted message (JWE) as input, decrypts, and prints the plaintext.
jose-util decrypt -k private-key.pem
Sign
Takes a payload as input, signs it, and prints the signed message with the embedded payload.
jose-util sign -k private-key.pem --alg PS256
Verify
Reads a signed message (JWS), verifies it, and extracts the payload.
jose-util verify -k public-key.pem
Expand
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
