Package jose aims to provide an implementation of the Javascript Object Signing
|
|
and Encryption set of standards. This includes support for JSON Web Encryption,
|
|
JSON Web Signature, and JSON Web Token standards.
|
|
|
|
**Disclaimer**: This library contains encryption software that is subject to
|
|
the U.S. Export Administration Regulations. You may not export, re-export,
|
|
transfer or download this code or any part of it in violation of any United
|
|
States law, directive or regulation. In particular this software may not be
|
|
exported or re-exported in any form or on any media to Iran, North Sudan,
|
|
Syria, Cuba, or North Korea, or to denied persons or entities mentioned on any
|
|
US maintained blocked list.
|
|
|
|
## Overview
|
|
|
|
The implementation follows the
|
|
[JSON Web Encryption](http://dx.doi.org/10.17487/RFC7516) (RFC 7516),
|
|
[JSON Web Signature](http://dx.doi.org/10.17487/RFC7515) (RFC 7515), and
|
|
[JSON Web Token](http://dx.doi.org/10.17487/RFC7519) (RFC 7519).
|
|
Tables of supported algorithms are shown below. The library supports both
|
|
the compact and full serialization formats, and has optional support for
|
|
multiple recipients. It also comes with a small command-line utility
|
|
([`jose-util`](https://github.com/square/go-jose/tree/v2/jose-util))
|
|
for dealing with JOSE messages in a shell.
|
|
|
|
**Note**: We use a forked version of the `encoding/json` package from the Go
|
|
standard library which uses case-sensitive matching for member names (instead
|
|
of [case-insensitive matching](https://www.ietf.org/mail-archive/web/json/current/msg03763.html)).
|
|
This is to avoid differences in interpretation of messages between go-jose and
|
|
libraries in other languages.
|
|
|
|
### Versions
|
|
|
|
We use [gopkg.in](https://gopkg.in) for versioning.
|
|
|
|
[Version 2](https://gopkg.in/square/go-jose.v2)
|
|
([branch](https://github.com/square/go-jose/tree/v2),
|
|
[doc](https://godoc.org/gopkg.in/square/go-jose.v2)) is the current version:
|
|
|
|
import "gopkg.in/square/go-jose.v2"
|
|
|
|
The old `v1` branch ([go-jose.v1](https://gopkg.in/square/go-jose.v1)) will
|
|
still receive backported bug fixes and security fixes, but otherwise
|
|
development is frozen. All new feature development takes place on the `v2`
|
|
branch. Version 2 also contains additional sub-packages such as the
|
|
[jwt](https://godoc.org/gopkg.in/square/go-jose.v2/jwt) implementation
|
|
contributed by [@shaxbee](https://github.com/shaxbee).
|
|
|
|
### Supported algorithms
|
|
|
|
See below for a table of supported algorithms. Algorithm identifiers match
|
|
the names in the [JSON Web Algorithms](http://dx.doi.org/10.17487/RFC7518)
|
|
standard where possible. The Godoc reference has a list of constants.

### Supported key types
|
|
|
|
See below for a table of supported key types. These are understood by the
|
|
library, and can be passed to corresponding functions such as `NewEncrypter` or
|
|
`NewSigner`. Each of these keys can also be wrapped in a JWK if desired, which
|
|
allows attaching a key id.
|
|
|
|
Algorithm(s) | Corresponding types
|

|
RSA | *[rsa.PublicKey](http://golang.org/pkg/crypto/rsa/#PublicKey), *[rsa.PrivateKey](http://golang.org/pkg/crypto/rsa/#PrivateKey)
|
|

|
[`jose-util`](https://github.com/square/go-jose/tree/v2/jose-util)
|
|
subdirectory also contains a small command-line utility which might be useful
|
|
as an example.
