# jose-jwe-fmt(1)

Converts a JWE between serialization formats

## NAME

jose-jwe-fmt - Converts a JWE between serialization formats

## SYNOPSIS

**jose jwe fmt** -i JWE \[-I CT\] \[-o JWE\] \[-O CT\] \[-c\]

## OVERVIEW

The **jose jwe fmt** command converts a JWE into alternative serialization formats. For example, it can:

 1\. Attach ciphertext to a detached JWE.

 2\. Detach ciphertext from a JWE.

 3\. Convert JWE Compact Serialization to JWE JSON Serialization.

 4\. Convert JWE JSON Serialization to JWE Compact Serialization.

## OPTIONS

• **-i** *JSON*, **--input**=*JSON* : Parse JWE from JSON

• **-i** *FILE*, **--input**=*FILE* : Read JWE from FILE

• **-i** -, **--input**=-: Read JWE from standard input

• **-I** *FILE*, **--detached**=*FILE* : Read decoded ciphertext from FILE

• **-I** -, **--detached**=- : Read decoded ciphertext from standard input

• **-o** *FILE*, **--output**=*FILE* : Write JWE to FILE

• **-o** -, **--output**=- : Write JWE to stdout (default)

• **-O** *FILE*, **--detach**=*FILE* : Detach ciphertext and decode to FILE

• **-O** -, **--detach**=- : Detach ciphertext and decode to standard output

• **-c**, **--compact** : Output JWE using compact serialization

## EXAMPLES

Attach ciphertext to a detached JWE and emit JWE Compact Serialization:

```
$ jose jwe fmt -i msg.jwe -I msg.ct -o compact.jwe -c
```

Detach ciphertext from a JWE:

```
$ jose jwe fmt -i msg.jwe -o detached.jwe -O detached.ct
```
