JavaScript Crypto Libraries

I start with a list and plan to create a comparison table.

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.

# VPN Namespace
# Uploaded to Gist by JimboMonkey1234

OS: Arch Linux
VPN: PIA/Mullvad
Requires: openvpn, openvpn-update-resolv-conf

Goals: 
 1) Force Deluge to use a VPN while leaving all other programs unaffected
 2) Introduce a killswitch to prevent Deluge from using anything other than the VPN
