23 July 2015 The  XML Security Working Group  has published a Group Note of  XML Signature Syntax and Processing Version 2.0 . This informative W3C Working Group Note describes XML digital signature processing rules and syntax. XML Signatures provide integrity, message authentication, and/or signer authentication services for data of any type, whether located within the XML that includes the signature or elsewhere.

19 February 2015 The Web Application Security Working Group has published a Candidate Recommendation of Content Security Policy Level 2 . This specification updates Content Security Policy, fine-tuning the existing policy options, and introducing a number of new mechanisms that site authors can use to mitigate the risk of content injection and related attacks. Major differences from Content Security Policy Level 1 may be found in Section 1.1 of the document . With this publication, we move the earlier edition off the Recommendation Track to a Note ( Content Security Policy 1.0 ) and invite implementers to share their experience with CSP Level 2.

22 August 2013 The Web Cryptography Working Group has published a Working Draft of WebCrypto Key Discovery . This specification describes a JavaScript API for discovering named, origin-specific pre-provisioned cryptographic keys for use with the Web Cryptography API. Pre-provisioned keys are keys which have been made available to the user agent by means other than the generation, derivation, importation functions of the Web Cryptography API. Origin-specific keys are keys that are available only to a specified origin. Named keys are identified by a name assumed to be known to the origin in question and provisioned with the key itself.

25 June 2013 The Web Cryptography Working Group has published a Working Draft of Web Cryptography API . This specification describes a JavaScript API for performing basic cryptographic operations in web applications, such as hashing, signature generation and verification, and encryption and decryption. Additionally, it describes an API for applications to generate and/or manage the keying material necessary to perform these operations. Uses for this API range from user or service authentication, document or code signing, and the confidentiality and integrity of communications. Learn more about the Security Activity .

08 January 2013 The Web Cryptography Working Group has published three documents . A Working Draft of Web Cryptography API . This specification describes a JavaScript API for performing basic cryptographic operations in web applications, such as hashing, signature generation and verification, and encryption and decryption. Additionally, it describes an API for applications to generate and/or manage the keying material necessary to perform these operations. Uses for this API range from user or service authentication, document or code signing, and the confidentiality and integrity of communications. A First Public Working Draft of WebCrypto Key Discovery . This specification describes a JavaScript API for discovering named, origin-specific pre-provisioned cryptographic keys for use with the Web Cryptography API. Pre-provisioned keys are keys which have been made available to the UA by means other than the generation, derivation, imporation functions of the Web Cryptog...

The Web Application Security Working Group has published the First Public Working Draft of User Interface Safety Directives for Content Security Policy . This document defines directives for the Content Security Policy mechanism to declare a set of input protections for a web resource's user interface, defines a non-normative set of heuristics for Web user agents to implement these input protections, and a reporting mechanism for when they are triggered. Learn more about the Security Activity .

13 September 2012 The Web Cryptography Working Group has published the First Public Working Draft of Web Cryptography API . This specification describes a JavaScript API for performing basic cryptographic operations in web applications, such as hashing, signature generation and verification, and encryption and decryption. Additionally, it describes an API for applications to generate and/or manage the keying material necessary to perform these operations. Key storage is provided for both temporary and permanent keys. Access to keying material is contingent on the same origin policy. Uses for this API range from user or service authentication, document or code signing, and the confidentiality and integrity of communications. Learn more about the Security Activity .

The Web Application Security Working Group has published the First Public Working Draft of Content Security Policy . This document defines Content Security Policy, a mechanism web applications can use to mitigate the broad class of content injection vulnerabilities, such as cross-site scripting (XSS). Content Security Policy is a declarative policy that lets the authors (or server administrators) of a web application restrict from where the application can load resources.
