T2DECODE
Offline-first cybersecurity and system learning platform (Flutter)
T2DECODE is an open-source (GPLv3) desktop application designed for learning cybersecurity, networks, and systems 100% offline. Developed by the TUTODECODE association, it follows the "Privacy by Design" principle: zero telemetry, zero cloud dependencies, and total sovereignty over your data. Key learning modules: - Networking: Subnet mask simulator and calculations. - System: Interactive chmod permission manager. - Cryptography: Local hash functions (SHA, MD5, etc.). - Local AI: Optional integration with Ollama to run LLMs (like Llama 3) locally for student assistance. Ideal for IT students (BTS SIO, BUT Informatique), air-gapped environments, or users in white zones without internet access. Built with Flutter for Windows, macOS, Linux, and Android. -

Open-Hashtool
Comfortable hash-tool for texts and files
Open-Hashtool is an easy2use Qt based application, which can be used to calculate the hash (MD4; MD5; SHA-1; SHA-224; SHA-256; SHA-384; SHA-512; SHA3-224; SHA3-256; SHA3-386; SHA3-512) of texts and files. It's compatible with Windows and Linux. But Linux users need Qt5.1 or Wine (configuration: Windows Version <= Windows 2008) to run the Open-Hashtool. Please read the Wiki for compiling instructions. -

Password Keeper + Generator
Free portable cross-platform graphical multi-user password manager
Free portable cross-platform multi-user password manager, 100%-pure Java. DB for each pkg-user is encrypted and protected by pkg-user hash. In addition - passwords in DB are stored in encrypted form. In result - stored passwords are double encrypted ! Passwords of pkg-users are not stored in program - stored and compared only hashes. Support md2, md5, sha1, sha256, sha384 and sha512 hash. Support export DB to CSV, HTML, XLS or XML and import from CSV, XLS or XML. Simple and intuitive GUI - Graphical User Interface. PKG use crypto security random generator. Developed with Java Spring Framework. Tested in Windows/Linux. Need Jre-1.8 - https://www.oracle.com/java/technologies/javase/javase8-archive-downloads.html. Source - https://github.com/harp077/pkg .

SSL Diagnos
SSL Strength Evaluation and Test Utility
SSL Diagnos is used to test SSL strength; get information about SSL protocols (pct, ssl2, ssl3, tls, dtls) and cipher suites. It can also be used for testing and rating ciphers on SSL clients. It has also specific support for pop3s, sip, smtp and explicit ftps. Tests for heartbleed (including dtls). Furthermore a separate tool, SSLPressure, not using openssl can be used to check the whole spectrum of possible SSL protocols on a server. Can also be used for testing ssl for mssql-servers (was added since nessus did not support this) and contains mitm poc for stripping ssl from mssql-connections. -

Simple Cipher Decoder
Decrypts and encrypts substitution, transposition and vigenere ciphers
Change log 1.01: 1)Error fixed on clicking solve and arrow buttons in the vigenere decoder 2)Error fixed when number of columns exceeds text length in substiution cipher 3)Can now handle variable block length when changing columns 4)Multiple identicle conversion values onn the frequency analysis page now not allowed This project is near its final stages but there may still be improvements to be made. If you could write some form of review or send me an email with advice I would greatly appreciate it. This is a series of three simple programs that will allow you to easily encrypt and decrypt text using any combination of substitutions, transpositions, vigenere ciphers or caesar shifts. The programs will not completely solve the ciphers for you haowever they will make it very clear to see how to solve them and ensure that there is no need for tedious manual work. -
