Application written in Python, that hides information from a file into a PNG image.

ImpraStorage provided a private imap access to store large files. Each file stored on the server is split in severals random parts. Each part also contains random noise data (lenght depends on a crypt key) to ensure privacy and exclude easy merge without the corresponding key. An index of files stored is encrypt (with the symmetric-key algorithm Kirmah) and regularly updated. Once decrypt, it permit to perform search on the server and download each part. transfert process is transparent. Just vizualize locally the index of stored files and simply select files to download or upload. ImpraStorage automatically launch the parts to download, then merge parts in the appropriate way to rebuild the original file. Inversely, a file to upload is split (in several parts with addition of noise data), and ImpraStorage randomly upload each parts then update the index.

KaHaShEr is an application to check the integrity of a file using MD5, SHA1, SHA256 and SHA512 checksum. Designed to be smart and easy to use, it includes a feature that can detect a hexadecimal value in the clipboard and automatically perform the verification while notifying you with a very expressive sound of the outcome of this verification.

Encryption with symmetric-key algorithm Kirmah - generate keys with exotic chars - redefine key length - key mark to ensure decryption capabilities - mix data - fast with multiprocessing - possible compression - gui on gtk3 - cli tool - python3 DEPENDENCIES : ======== python3, python-gobject, gobject-introspection, pygtk 3 modes are available to encrypt : ======== - compression (full / disabled or only final step) - random (simulate a random order - based on crypted key - to randomize data) - mix (mix data according to a generated map - based on crypted key - with addition of noise) Process is as follow : ======== encrypt : file > [ compress > ] encrypt > [randomiz data > mix data > compress > ] file.kmh decrypt: file.kmh > [ uncompress > unmix data > unrandomiz data] > decrypt > [uncompress > ] file ======== for encrypt/decrypt large binary files, use the fastest alternative : split/merge

Development area for GNU/Linux 2.6.x for the KS8695 ARM SoC. Covers kernel patches, drivers for serial, Ethernet, PCI, GPIO, watchdog subsystems, and drivers for optional PCI based devices such as USB, WiFi, WiMAX, IPSec, SSL, and RSA devices.

Merovingian is very easy to use but powerful GUI interface for GnuPG. It intends to be well integrated with GNOME, but still usable with other desktop environments too.

This repository contains the standalone desktop application from the Midbar project. The app operates entirely offline and does not require an internet connection. GitHub repository: https://github.com/Northstrix/Midbar-Desktop-App

A version of Midbar data vault adapted for the ESP32 CYD and WebFlash. It keeps the cryptographic keys in the ESP32 RAM and stores the ciphertexts (encrypted data) in the Google Firebase. The tutorial is available at: https://www.instructables.com/How-to-Turn-ESP32-CYD-Into-a-Secure-IoT-Data-Vault/ WebFlash for ESP32-CYD: https://northstrix.github.io/Midbar-ESP32-CYD-Firebase-Edition/flash WebFlash for ESP32-CYD2USB: https://northstrix.github.io/Midbar-ESP32-CYD2USB-Firebase-Edition/flash

OpenPortalGuard is a flexible, extensible, and massively scalable access control system for portals. It provides single-sign-on features for username/pw and smartcards as well as declarative access control.

The OpenCoin project provides resources for creating virtual currencies: documentation, format and protocol definitions, an open-source reference implementation for issuers, users and traders. It is based on David Chaum's electronic cash concept.

Petoron Crypto Archiver (PCA) Key features: AES-256-CFB encryption with unique IV per archive Argon2id key derivation (256MB RAM / time_cost=3 / parallelism=4) HMAC-SHA512 integrity and anti-tampering check No compression, no fingerprinting, no trace of original data Works with both single files and entire directories Fully CLI-based, portable, and open format (.pca) https://github.com/01alekseev/PCA

PGP Individual UID Signer makes signing all the UIDs on all of the keys at a PGP Keysigning party much simpler. It prompts for verification fingerprints, and then signs each UID on each key separately and PGP/Mime encrypt-emails them to their recipient. NOTE: Developement now happens at GitHub: http://github.com/jaymzh/pius

The aim of this small program is to parse your address book (Evolution address book or VCard file for the moment) and check if some of your contacts have uploaded a PGP public key on a key server.

Petoron Local Destroyer (PLD) Features: 10-pass default cryptographic overwrite (customizable) Argon2id + AES-CFB entropy stream per session No logs, no caching, no backups Full CLI control (purge, wipe) Clean TRASH/workflow If you want your files to truly disappear — not just be deleted - PLD is the tool. https://github.com/01alekseev/PLD

Petoron Quantum Standard (PQS) v1.2 A fully custom, offline encryption standard - built entirely from scratch. PQS v1.2 is a minimalistic, self-contained encryption engine for secure file protection, with zero reliance on external cryptographic libraries. PBKDF2-HMAC-SHA256 (200k iterations, adjustable) for password hardening. Key separation via BLAKE2s - independent keys for encryption and MAC. BLAKE2s-MAC authentication - 16-byte tag, any modification = instant rejection. Streaming keystream generator - secure, large-scale XOR without key reuse. Fake padding (HEAD/TAIL) - obfuscates binary boundaries and payload structure. Precise size encoding - restores original payload exactly. Supports files up to 128 MB per encrypted block. No dependencies, fully offline, cross-platform Python implementation. PQS is designed for high-assurance security, full auditability, and deterministic offline use - without unnecessary complexity. https://github.com/01alekseev/PQS

Petoron Seal Contracts (PSC) Fully binary .psc contract format TTL (time to live) built-in Ed25519 participant signatures Executed-flag to prevent reuse External .sig signature support Fully offline and P2P-ready Compatible with Petoron Time Burn Cipher (PTBC) https://github.com/01alekseev/PSC

Petoron Time Burn Cipher (PTBC) A promising cipher based on self-destruction of time, complete absence of traces and impossibility of key selection. Key features: AES-CFB encryption with per-file IV Argon2id key derivation with 256MB RAM resistance TTL (time to live) built directly into the encrypted file HMAC-SHA512 integrity verification Self-deleting mode (--autowipe) and one-time access marking (--onetime) No file metadata, no recovery, no password resets Philosophy: If you lose the password - it’s over. If time expires - it’s gone. PTBC doesn’t forgive, doesn’t forget, and doesn’t leak. https://github.com/01alekseev/PTBC

ParaCrypt is software for encrypting and decrypting data with one-time-pads. For convenience the one-time-encryption-pads are created using pre-shared unencrypted files as sources of entropy.

PassEncryption uses RSA encryption method to generate passwords for each accounts with a personal encryption key. Windows 7 and more only. IMPORTANT: Current release doesn't work with 32 bits architectures, will be fixed in next update

Pena is an acronym for "Pena Encryption for Automata". This framework will help you to run encrypted representations of programs.
