The Stanford Javascript Crypto Library is a project by the Stanford Computer Security Lab to build a secure, powerful, fast, small, easy-to-use, cross-browser library for cryptography in Javascript. SJCL is secure. It uses the industry-standard AES algorithm at 128, 192 or 256 bits; the SHA256 hash function; the HMAC authentication code; the PBKDF2 password strengthener; and the CCM and OCB authenticated-encryption modes.

OpenSSH encrypts all traffic (including passwords) to effectively eliminate eavesdropping, connection hijacking, and other attacks. Additionally, OpenSSH provides secure tunneling capabilities and several authentication methods, and supports all SSH protocol versions.
 
The OpenSSH suite replaces rlogin and telnet with the ssh program, rcp with scp, and ftp with sftp. Also included is sshd (the server side of the package), and the other utilities like ssh-add, ssh-agent, ssh-keysign, ssh-keyscan, ssh-keygen and sftp-server.

OpenSSH - Keep your communication secret

JSch is a pure Java implementation of SSH2. JSch allows you to connect to an sshd server and use port forwarding, X11 forwarding, file transfer, etc., and you can integrate its functionality into your own Java programs.

The gnupg module allows Python programs to make use of the functionality provided by the GNU Privacy Guard (abbreviated GPG or GnuPG). Using this module, Python programs can encrypt and decrypt data, digitally sign documents and verify digital signatures, manage (generate, list and delete) encryption keys, using proven Public Key Infrastructure (PKI) encryption technology based on OpenPGP.

The OpenCA PKI Development Project is a collaborative effort to develop a robust, full-featured and Open Source out-of-the-box Certification Authority implementing the most used protocols with full-strength cryptography world-wide.  The project development is divided in two main tasks: studying and refining the security scheme that guarantees the best model to be used in a CA and developing software to easily setup and manage a Certification Authority.

Tcpcrypt is a protocol that attempts to encrypt (almost) all of your network traffic. Unlike other security mechanisms, Tcpcrypt works out of the box: it requires no configuration, no changes to applications, and your network connections will continue to work even if the remote end does not support Tcpcrypt, in which case connections will gracefully fall back to standard clear-text TCP.
 
We might be already using SSL, HTTPS, VPN in our network. Those solutions are inadequate for ubiquitous encryption. For example, almost all solutions rely on a PKI to stop man-in-the-middle attacks, which for ubiquitous deployment would mean that all Internet users would have to get verified by a CA like Verisign and have to spend money to buy a certificate. Tcpcrypt abstracts away authentication, allowing any mechanism to be used, whether PKI, passwords, or something else. 
 
Tcpcrypt has very high performance (up to 25x faster than SSL), making it feasible for high volume servers to enable encryption on all connections.
