NAME

jose-jwe-dec - Decrypts a JWE using the supplied JWKs

SYNOPSIS

jose jwe dec -i JWE [-I CT] -k JWK [-p] [-O PT]

OVERVIEW

The jose jwe dec command decrypts a JWE using one or more JWK (-k) or password (-p). Decryption succeeds if any key is able to perform decryption.

If the JWE is a detached JWE, meaning that the ciphertext is stored in binary form external to the JWE itself, the ciphertext can be loaded using the -I parameter.

Please note that, when specifying the -O option to output the plaintext, plaintext output begins before ciphertext validation. Therefore, you must check the return value of the command before using the data.

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
-p, --password: Prompt for a decryption password, if necessary
-k FILE, --key=FILE: Read JWK(Set) from FILE
-k -, --key=-: Read JWK(Set) from standard input
-O JSON, --detach=JSON: Parse JWE from JSON
-O FILE, --detach=FILE: Read JWE from FILE
-O -, --detach=-: Read JWE from standard input

EXAMPLES

Decrypt a JWE with a JWK:

$ jose jwe dec -i msg.jwe -k rsa.key -O msg.txt

Decrypt a JWE with a password:

$ jose jwe dec -i msg.jwe -p -O msg.txt
Please enter decryption password:

Decrypt a JWE with either of two JWKs:

$ jose jwe dec -i msg.jwe -k ec.jwk -k rsa.jwk -O msg.txt
