Open Source Tcl Cryptography Software for Windows

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/

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

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

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!

Crypto.mod is a simple LOADABLE cryptographic module for tcl 8.3+ (possibly older, not tested). The module supports the blowfish, twofish and rijndael ciphers.

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.

OS based on Agent based Security with a new type of split kernel and agents platform.

A set of tools for manipulating and solving pencil-and-paper style ciphers, cryptograms, and related puzzles.

Fast cryptography extension for Tcl. TclTomCrypt is a sensible binding that brings the features and performance of LibTomCrypt to Tcl.

RSA Public Key Crypotgraphy for Web Browsers. Use JavaScript to RSA-encrypt data that can only be decrypted on the server, and not by prying eyes. The poor man's SSL...
