The WebCrypto API is meant to solve this but many aspects of it are not quite ready for production yet. I'd personally love to see JS crypto libraries like CryptoJS, SJCL and Forge start implementing polyfills for WebCrypto. Even just using the getRandomValues method (which seems to be fairly stable across all modern browsers) for their PRNG implementations would result in a much more theoretically sound crypto library. http://www.w3.org/TR/WebCryptoAPI/ http://www.w3.org/TR/WebCryptoAPI/ https://github.com/digitalbazaar/forge https://github.com/digitalbazaar/forge https://github.com/bitwiseshiftleft/sjcl https://github.com/bitwiseshiftleft/sjcl https://code.google.com/p/crypto-js/ https://code.google.com/p/crypto-js/
