JavaScript Crypto Libraries

List some crypto libraries for JavaScript out there. Might be a bit out dated. Scroll to the bottom.

WebCryptoAPI

http://www.w3.org/TR/WebCryptoAPI/

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.

Before you begin

Make sure you have adb installed and that it works. Test this by connecting your phone and running adb devices. In order to proceed past the build stage, your device must be rooted. The device I used is running Cyanogenmod with root enabled for both apps and adb.

Build

Fetch the Android NDK

You'll need to get the Android NDK. I used r8e, which you can get from here: http://dl.google.com/android/ndk/android-ndk-r8e-linux-x86.tar.bz2. Make sure you get the x86 version, as the x86_64 version will not help you. Let's call the path where you unpack this NDK_PATH.
