As of 2017, this Working Group is now closed.
Maintenance for the W3C Recommendation happens under the supervision of the Web Security Interest Group.
The Web Cryptography Working Group developed a Recommendation-track document that defines an API that lets developers implement secure application protocols on the level of Web applications, including message confidentiality and authentication services, by exposing trusted cryptographic primitives from the browser. This will promote higher security insofar as Web application developers will no longer have to create their own or use untrusted third-party libraries for cryptographic primitives.
