NAME

6       jose-jwe-enc - Encrypts plaintext using one or more JWK/password
7

SYNOPSIS

9       jose jwe enc [-i JWE] -I PT -k JWK [-p] [-r RCP] [-o JWE] [-O CT] [-c]
10

OVERVIEW

12       The jose jwe enc command encrypts data using one or more JWK (-k) or
13       password (-p). When specifying more than one JWK or password,
14       decryption will succeed with any one of the provided keys.
15
16       A detached JWE can be created by specifying the -O option. In this
17       case, the decoded ciphertext will be written to the output specified
18       and will not be included in the JWE.
19
20       If only one key is used (-k or -p), the resulting JWE may be output in
21       JWE Compact Serialization by using the -c option.
22
23       This command uses a template based approach for constructing a JWE. You
24       can specify templates of the JWE itself (-i) or for the JWE Recipient
25       Object (-r). Attributes specified in either of these templates will
26       appear unmodified in the output. One exception to this rule is that the
27       JWE Protected Header should be specified in its decoded form in the
28       template. This command will automatically encode it as part of the
29       encryption process.
30
31       If you specify a JOSE Header Parameter (via either the -i or -r
32       options) that affects the construction of the JWE, this command will
33       attempt to behave according to this parameter as if it were
34       configuration. For example, specifying the "zip" parameter in the JWE
35       Protected Header will cause the plaintext to be compressed before
36       encryption. Currently, jose will modify its behavior for the "alg",
37       "enc" and "zip" JOSE Header Parameters (see RFC 7516 Section 4.1.3), as
38       well as the algorithm-specific parameters for the algorithms we support
39       (see RFC 7518 Section 4).
40
41       However, it is not necessary to provide any templates: jose jwe enc
42       will automatically fill in the "alg" and "enc" parameters by inferring
43       the correct algorithms from the provided input keys (JWK or password).
44       Therefore, the -i and -r options should generally be used for providing
45       extended JWE metadata.

EXAMPLES

80       Encrypt data with a symmetric key using JWE JSON Serialization:
81
82           $ jose jwk gen -i '{"alg":"A128GCM"}' -o key.jwk
83           $ jose jwe enc -I msg.txt -k key.jwk -o msg.jwe
84
85       Encrypt data with a password using JWE Compact Serialization:
86
87           $ jose jwe enc -I msg.txt -p -c -o msg.jwe
88           Please enter an encryption password:
89           Please re-enter the previous password:
90
91       Compress plaintext before encryption:
92
93           $ jose jwe enc -i '{"protected":{"zip":"DEF"}}' ...
94
95       Encrypt with two keys and two passwords: $ jose jwk gen -i

97       -o rsa.jwk $ jose jwe enc -I msg.txt -p -k ec.jwk -p -k rsa.jwk -o
98       msg.jwe Please enter a password: Please re-enter the previous password:
99       Please enter a password: Please re-enter the previous password:
