+
+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.

+# Safe JSON
+
+This repository contains a fork of the `encoding/json` package from Go 1.6.
+
+The following changes were made:
+
+* Object deserialization uses case-sensitive member name matching instead of
+  [case-insensitive matching](https://www.ietf.org/mail-archive/web/json/current/msg03763.html).
+  This is to avoid differences in the interpretation of JOSE messages between
+  go-jose and libraries written in other languages.
+* When deserializing a JSON object, we check for duplicate keys and reject the
+  input whenever we detect a duplicate. Rather than trying to work with malformed
+  data, we prefer to reject it right away.
