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.

Secure sessions with Node.js, Express.js, and NginX as an SSL Proxy
Secure sessions are easy, but not very well documented.
Here's a recipe for secure sessions in Node.js when NginX is used as an SSL proxy:
The desired configuration for using NginX as an SSL proxy is to offload SSL processing
and to put a hardened web server in front of your Node.js application, like:
[NODE.JS APP] <- HTTP -> [NginX] <- HTTPS -> [PUBLIC INTERNET] <-> [CLIENT]
Edit for express 4.X and >: Express no longer uses Connect as its middleware framework, it implements its own now.

Instructions for exporting/importing (backup/restore) GPG keys

Every so often I have to restore my gpg keys and I'm never sure how best to do it. So, I've spent some time playing around with the various ways to export/import (backup/restore) keys.

Method 1

Backup the public and secret keyrings and trust database

cp ~/.gnupg/pubring.gpg /path/to/backups/
cp ~/.gnupg/secring.gpg /path/to/backups/
cp ~/.gnupg/trustdb.gpg /path/to/backups/

or, instead of backing up trustdb...
