NAME

       jose-jwe-enc - Encrypts plaintext using one or more JWK/password

SYNOPSIS

       jose jwe enc [-i JWE] -I PT -k JWK [-p] [-r RCP] [-o JWE] [-O CT] [-c]

OVERVIEW

The jose jwe enc command encrypts data using one or more JWK (-k) or password (-p). When specifying more
than one JWK or password, decryption will succeed with any one of the provided keys.

A detached JWE can be created by specifying the -O option. In this case, the decoded ciphertext will be
written to the output specified and will not be included in the JWE.

If only one key is used (-k or -p), the resulting JWE may be output in JWE Compact Serialization by using
the -c option.

This command uses a template based approach for constructing a JWE. You can specify templates of the JWE
itself (-i) or for the JWE Recipient Object (-r). Attributes specified in either of these templates will
appear unmodified in the output. One exception to this rule is that the JWE Protected Header should be
specified in its decoded form in the template. This command will automatically encode it as part of the
encryption process.

If you specify a JOSE Header Parameter (via either the -i or -r options) that affects the construction of
the JWE, this command will attempt to behave according to this parameter as if it were configuration. For
example, specifying the "zip" parameter in the JWE Protected Header will cause the plaintext to be
compressed before encryption. Currently, jose will modify its behavior for the "alg", "enc" and "zip"
JOSE Header Parameters (see RFC 7516 Section 4.1.3), as well as the algorithm-specific parameters for the
algorithms we support (see RFC 7518 Section 4).

However, it is not necessary to provide any templates: jose jwe enc will automatically fill in the "alg"
and "enc" parameters by inferring the correct algorithms from the provided input keys (JWK or password).
Therefore, the -i and -r options should generally be used for providing extended JWE metadata.

EXAMPLES

       Encrypt data with a symmetric key using JWE JSON Serialization:

           $ jose jwk gen -i ´{"alg":"A128GCM"}´ -o key.jwk
           $ jose jwe enc -I msg.txt -k key.jwk -o msg.jwe

       Encrypt data with a password using JWE Compact Serialization:

           $ jose jwe enc -I msg.txt -p -c -o msg.jwe
           Please enter an encryption password:
           Please re-enter the previous password:

       Compress plaintext before encryption:

           $ jose jwe enc -i ´{"protected":{"zip":"DEF"}}´ ...

       Encrypt  with  two  keys and two passwords: $ jose jwk gen -i ´{"alg":"ECDH-ES+A128KW"}´ -o ec.jwk $ jose
       jwk gen -i ´{"alg":"RSA1_5"}´ -o rsa.jwk $ jose jwe enc -I msg.txt -p -k ec.jwk -p -k rsa.jwk -o  msg.jwe
       Please  enter a password: Please re-enter the previous password: Please enter a password: Please re-enter
       the previous password:
