Open Source Tcl Security Software

Network Security Toolkit (NST) is a bootable ISO image (Live USB Flash Drive) based on Fedora 42 providing easy access to best-of-breed Open Source Network Security Applications and should run on most x86_64 systems. The main intent of developing this toolkit was to provide the security professional and network administrator with a comprehensive set of Open Source Network Security Tools. The majority of tools published in the article: Top 125 Security Tools by INSECURE.ORG are available in the toolkit. An advanced Web User Interface (WUI) is provided for system/network administration, navigation, automation, network monitoring, host geolocation, network analysis and configuration of many network and security applications found within the NST distribution. In the virtual world, NST can be used as a network security analysis, validation and monitoring tool on enterprise virtual servers hosting virtual machines.

Self contained and completely portable binary encrypts text for secure email, messaging, irc use, etc., ideal for USB flash drives. AES-128/192/256 (ecb/cbc), Blowfish (ecb/cbc), DES / TripleDES (ecb/cbc/ofb/cfb), or RC4. Linux and Windows binaries. I don't make cute interfaces, it just works. https://codeberg.org/BloodFeastMan/pte I would also recommend FTC, encrypts both files and text using the same interface as PTE, and a separate encryption and hashing engine I wrote in Crystal, and is much faster than PTE: https://sourceforge.net/projects/ft-crypt/

FTC cascades choice of Aria-256, AES-256, Camellia-256, SM4, or ChaCha20 for file and text encryption, the keystream generation is extremely robust I don't make cute interfaces, it just works.

Hexadecimal and raw packet injector and sniffer. Can be easily combined with other tools to provide a powerful cmdline framework for raw network access.

Sguil's (pronounced sgweel) main component is an intuitive GUI that receives realtime events from snort/barnyard. It includes other components which facilitate the practice of Network Security Monitoring (NSM) and event driven analysis of IDS alerts.

TclTrf is an extension library to the script language tcl, as created by John Ousterhout. It extends the language at the C-and Tcl-with ``transformer''-commands to encode and compress data. Based on the stacked channels of the tcl core (ability inter

Tiny script will find hash digest of files or text by calling on Microsoft's "certutil.exe", using MD4, MD5, SHA1, SHA256, SHA384, or SHA512. Simple and self explanatory. *EDIT 5/3/25, I just realized that there is another project entitled "WinHasher", it appears to kind of do the same thing but uses native code rather than Microsoft's "certutil". If that's what you're looking for, it's here: https://github.com/gpfjeff/winhasher

Hashes, encrypts, and encodes lousy passwords based information from initial hashes, combined with user provided offsets. Creating easy to memorize systems of passwords and offsets, the possibilities are endless, with never a need to file your passwords to disc or entrust them to a password manager.

An original bruteforce-based encryption/decryption system. BBE was originally conceived to chat with encrypted text on IRC. mIRC and X-Chat support BBE via script addon. BBE can also encrypt MIME encoded files. Blowfish encryption is currently supported.

The Desktop Environment For Kids is a kid friendly environment for UNIX/Linux, complete with kid oriented desktop themes and desk accesories.

This is a stripped down, no nonsense, no options encryption utility for normal users who just want to secure their files and text and move on. The ciphers used are Aria-256, AES-256, and Blowfish-448 in OFB and CBC mode. The password hashing and salt derivation are robust. I don't make cute interfaces, it just works.
