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.

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

OpenSignature is an open source project for the digital signature of documents. It works with all cards supported by OpenSC and focuses on adding support for cards from accredited Italian CAs. The goal of the project is to provide a first single product

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/

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

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

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.

A Secure, Firewall-Friendly Platform for Peer-to-Peer Networking. With a few mouse clicks, request remote access to colleagues' computer desktops, transfer files, sketch & chat, or videoconference. Automatic, authenticated & encrypted tunneling!

Most file hashing utils involve specifying a file in a dialog, or dragging a file to an input box, SDigest simply resides in the file context menu, and will display a pop-up showing MD5, SHA1, SHA256, and SHA512 message digests of the selected file

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.
