Overview

from gopkg.in/square/go-jose.v1

from gopkg.in/square/go-jose.v1

Package jose aims to provide an implementation of the Javascript Object Signing and Encryption set of standards. For the moment, it mainly focuses on encryption and signing based on the JSON Web Encryption and JSON Web Signature standards. The library supports both the compact and full serialization formats, and has optional support for multiple recipients.
