IMPORTANT NOTICE (Jun 1, 2015)
The jsjws is now merged into jsrsasign and any further update for jsjws will be done only in jsrsasign. So please move to jsrsasign. Thank you.
JSON Web Signature(JWS) is a specification for signing JSON data structure defined in OpenID community [1] and IETF [2] and one of basic component for OpenID ABC or OpenID Connect. The 'jsjws'(JSON Web Signature JavaScript Library) is a pure open source free JavaScript implementation of it. Furthermore, 'jsjws' provides JSON Web Signature JSON Serialization (JWS-JS) [3] which is a kind of parallel or independent signature format by multiple signers.

WHAT IS JWS?

JSON Web Signature(JWS) is a simple signature format for signing small JSON data and will be used to exchange an authentication data for OpenID Connect. Any JWS data is represented in a printable text since it consists of Base64URL encoded characters and period('.'). Following figure shows how JWS signature will be generated.

See following pages for detail.

WHAT IS JWS-JS?

JSON Web Signature JSON Serialization (JWS-JS) is a signature format to sign a data by a number of signers independently. This way of signing is called parallel or independent signature in general. Following figure shows how JWS-JS signature will be generated.
