+# 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
