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.
Sportal is made for people that need to know what is going on in their systems. It monitors files that you select, for "hot words" that you also select, through a graphical interface. When a hot word is found in the file being watched, it will let you know. There is no restriction on the numbers of files or hot words.
Sort-of-pronounceable-password generator is a Perl script that generates easy-to-remember passwords. The following variables can be specified: the number of passwords, the length of the passwords, the dictionary file, the length of the chunks of words that are used to construct the password, and the character to separate the passwords in the output.
Smit is an ARP-level transproxy/sniffer, capable of relaying local traffic even in switched environment. The source is based on the arprelay and arpmitm tools, but offers a nice command line interface and option of saving raw packets into a file. It includes some tricky techniques for ARP-cache consistence. You can also run Smit in transproxy-only mode and use your favourite sniffer to capture 'hijacked' packets, and it includes a ring buffer option for high performance packet capture.
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.
SIDEN is a distributed network discovery tool used for intrusion detection research. The current SIDEN architecture allows you to simulate coordinated/distributed network probes by a group of attackers. Using it, you can simulate such probes against one target or many targets. The point of this is to generate the traffic caused by distributed network probes, so that it can be analyzed for better understanding of distributed network probes. This will hopefully help us to improve how Intrusion Detection Systems are written.
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.
SecureNet PRO is a network monitoring and intrusion detection platform. It combines powerful scripting functionality with real-time session viewing and control capabilities. It goes beyond network-grep and signature-based intrusion detection offerings, offering a combination of true state-based decoding of application-layer protocol traffic and high-speed pattern matching. It offers full IP fragment reassembly functionality, TCP session reconstruction, and an advanced TCP/IP stack emulation facility.
