The sigs package provides secure digital signatures with verification at secret-key speeds. 2048-bit verification on a Pentium-100 takes under 150 microseconds; for comparison, encrypting 2048 bits with the fastest available DES implementation takes 113 microseconds.

SILC (Secure Internet Live Conferencing) is a protocol which provides secure conferencing and chat services. It can be used to send any kind of messages, in addition to normal text messages, including multimedia messages like images, video, and audio stream. All messages in the SILC network are encrypted and authenticated, and messages can also be digitally signed. SILC protocol supports AES, SHA-1, SHA-2, PKCS#1, PKCS#3, X.509, OpenPGP, and is being developed in the IETF. The software is delivered as SILC Client for end users, SILC Server for system administrators, and SILC Toolkit for application developers.

SmartSign is a set of modules which allow integration of smartcard technology into an OpenCA based Public Key Infrastructure in order to provide smartcard-based digital signature and local authentication security services. It allows direct signing of e-mail and e-news from within Netscape using smartcards and supports signing of generic files from command line. The package includes a PAM module too, which allows system administrators to integrate smartcard-based authentication for local users. A modified version of the OpenSSH client allows secure authentication to a remote server. A couple of command line tools allow signing and verifying generic files from the shell. Finally, a command line interactive shell supports all operations on the card, and can be used to write scripts that automate particular tasks on the card. Currently only Schlumberger Cyberflex Access 16K is supported.

SSH (Secure Shell) is a program to log into another computer over a network, to execute commands in a remote machine, and to move files from one machine to another. It provides strong authentication and secure communications over insecure channels. It is intended as a replacement for rlogin, rsh, rcp, and rdist.

ssldump is an SSLv3/TLS network protocol analyzer. It identifies TCP connections on the chosen network interface and attempts to interpret them as SSLv3/TLS traffic. When it identifies SSLv3/TLS traffic, it decodes the records and displays them in a textual form to the console. If provided with the appropriate keying material, it will also decrypt the connections and display the application data traffic.

StegFS is a steganographic file system for Linux. It offers security beyond that afforded by a regular cryptographic file system, since it not only encrypts data, but also provides a plausible deniability mechanism by securely hiding the data. It is designed to give the user a very high level of protection against being compelled to disclose its contents. StegFS extends the standard Linux file system (ext2fs), allowing normal and several levels of hidden files to coexist. This allows some data to remain hidden even if some of the keys are compromised.

Steghide is a steganography program that is able to hide data in various kinds of image and audio files. The color-frequencies (for image files) or sample-frequencies (for audio files) are not changed, thus making the embedding resistant against first-order statistical tests. Features of steghide include compression and encryption of embedded data, embedding of a checksum to verify the integrity of the extracted data, and support for JPEG, BMP, WAV, and AU files.

Strip is a password and account management program for the Palm Computing Platform. Designed to fit the needs of both IT professionals and the average user, it combines ease of use with flexibility and security. 128 bit encryption ensures that even if your Palm Pilot is lost or stolen your important account and password information will remain confidential. Strip has a quick and easy to use interface, with many useful features including the ability to beam shared accounts to other Strip users.

The stunnel program is designed to work as an SSL encryption wrapper between remote client and local (inetd-startable) or remote server. It can be used to add SSL functionality to commonly used inetd daemons like POP2, POP3, and IMAP servers without any changes in the programs' code. It will negotiate an SSL connection using the OpenSSL or SSLeay libraries. It calls the underlying crypto libraries, so stunnel supports whatever cryptographic algorithms you compiled into your crypto package.

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.
