PolyCrypt - A JavaScript Library Implementing The WebCrypto Polyfill

PolyCrypt is a JavaScript library which implements the  W3C WebCrypto API for the DOM.  This API is meant to expose a JavaScript interface to your web applications for performing various cryptographic tasks 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. This API is meant to be used for user/service authentication, document/code signing as well as for ensuring confidentiality and integrity of communications.

While the WebCrypto  API is still a work in progress, PolyCrypt is an implementation of the API in pure JavaScript, which can be used as a testing ground for the new API or as a polyfill for browsers which will not be able to upgrade to implement the WebCrypto API.

jsSHA - A JavaScript Implementation Of The Entire Family Of SHA Hashes

jsSHA is a JavaScript implementation of the entire family of SHA hashes as defined in FIPS 180-2 (SHA-1, SHA-224, SHA-256, SHA-384, and SHA-512) as well as HMAC. Despite JavaScript not natively supporting 64-bit operations, SHA-384 and SHA-512 are even implemented! jsSHA is also 100% cross-browser compatible.
