Lava's jDES is a highly optimized, highly configurable implementation of the Data Encryption Standard (DES) in Java. jDES was designed with four goals in mind: accuracy, speed, ease of use, and configurability. jDES utilizes Sharkysoft's proprietary reformulation of DES optimized for 32-bit machines. jDES was initially released as an integrated feature of Lava, a general-purpose class library for Java. By popular demand, it is now distributed in its own bundle.

trf is an extension library to the script language tcl, as created by John Ousterhout. It extends the language at the C-level with so-called "transformer"-procedures. With the help of some patches to the core the package is able to intercept all read/write operations on designated channels, thus giving it the ability to transform the buffer contents as desired. Existing transforms include Base64, UUencode, Hashes (SHA, MD5, ...), error correction codec, zlib-based compression, script level transforms.

trfcrypt is an add-on package to the Tcl-extension trf. It provides the encryption functionality which was removed from the base package (Trf) to allow its inclusion on the Tcl/Tk CD-ROM without violating US export control laws on cryptography.

TEA Total is a collection of extremely small encryption tools. At the heart of TEA Total is the TEA (Tiny Encryption Algorithm): a fast and secure 128-bit private key algorithm which was developed and placed in the public domain by David Wheeler and Roger Needham of the Cambridge Computer Laboratory.

Given a threshold t, sharesecret splits a secret into parts, such that exactly t parts are needed to reconstruct the secret. If you have fewer parts you know only the approximate or exact length of the secret.

shsecret takes a file and splits it into N parts of equal size such that any M parts can be used to reconstruct the secret, but fewer than M will give absolutely no information about the secret. This program is written in strict ANSI C, so it should be completely portable. It is also hopefully simpler and more efficient than other implementations of the same algorithm.

Secure Remote Password (SRP) is a password-based authentication and key exchange mechanism where no information about the password is leaked during the authentication process. It does not require any public key cryptography, yet even if one were to eavesdrop on the authentication process, no information which would aid in guessing the password can be obtained (in theory). There are some reworked Telnet and FTP clients and servers available already.

Sendmail-TLS is a wrapper for Sendmail which allows for clients to make a secure (SSL) connection to their mailserver as described in RFC 2487. The connection is internally forwarded to sendmail and does not require sendmail to be running on port 25. Clients which support this currently are Netscape Messenger, Microsoft Outlook, and Microsoft Outlook Express.
