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

PassEncryption is a software written in python designed to encrypt and decrypt files as well as generating passwords. 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

PassLock is a password manager and password generator that encrypts passwords using AES and saves them securely on your local machine. The password is encrypted and decrypted using a user-defined key and will get updated in each use. Extending the length of the private key will steadily improve the overall security. PassLock also generates a 40-bit long password consisting of lowercase, uppercase letters, numbers, and symbols Passlock's 220bit AES encryption and infinitely long password generator make your passwords nearly impossible to break and Its Console Based User Interface will definitely help to enhance your experience.

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

Protect My Docs is a free watermarking tool for PDF and image files. Add a fully customizable text watermark with AES-128 encryption, ZIP AES-256 export, and mail optimization. No Python installation required. Available for Windows, macOS, and Linux.

Simple python program to encrypt up to 255 character text into .png or .bmp images. VIEW the README for further instructions as well as image specifications. Used pyinstaller to compile into an .exe ---Feedback is welcome ---

We're working on developing a standard encryption API for the Python language, and building a set of standard cryptography modules. The CVS tree is open to anyone who needs it for a Python/crypto related package.

Visual Cryptography is a graphical form of information concealing. In a 2-out-of-2 Visual Cryptography Scheme a dealer will "split" a secret image into two shares, print the shares onto separate transparencies and hand them to the participants to the scheme. If the two participants come together, they'll be able to reveal the secret image without a computer, perfectly superimposing the transparencies they own. Analyzing a single share, no one will be able to obtain any information considering the secret image no matter the computing or the analyzing power. In an Extended Visual Cryptography Scheme, both the secret image and the shares are meaningful images like a landscape, a building or a beautiful girl, hiding the very intention to conceal a secret. PyEvcs is a command line Python application allowing you to experiment with Extended Visual Cryptography Schemes for "natural" continuous tone images.

PyGFS is a reliable and secure distributed file system that runs completely in userspace. It supports x509 certificate authentication, authorization and encryption mechanisms to provide secure access over insecure networks.

PyGestPayCrypt is the Python implementation of GestPayCrypt and GestPayCryptHS classes for italian Banca Sella GestPay online credit card payment system.

PyMe is a Python interface to GnuPG functions. It is based on GPGME library.

https://www.garanet.net/it-blog/python-password-manager/ A Python3 Password Manager, with encryption and without an Internet connection. How it Works: First Run: PyPWD > Creates Master Key with your master username and password (Do not forget it or modify the config file, otherwise you'll be not able to open your password manager anymore). PyPWD > Saves a DataFrame as an encrypted CVS and all passwords are encrypted too, with key and the master password. Login: PyPWD > Dencrypts the password file, based on the username and password filled.

PyPassMan is a password manager that allows user to store passwords and password-related informations. It uses a strong cryptographic library to ensure information security. Its aim is to organize those informations in a simple and efficient way.

PyPasswordSafe is a Python module for reading, searching, and displaying PasswordSafe v3 (http://passwordsafe.sourceforge.net) data files.

PyTextCryptor is a simple python program to encrypt text, and easy to use. I can save to a file(.cro). It uses PygGtk, and python.

A small collection of pure-Python cryptography algorithms.

Python OpenSSL Wrappers(POW), a Python wrapper for OpenSSL. X590v3 and CRL encoding is now also support is now via a pure Python module, which will include support for PKCS in the near future.

RotNN is a Python module that implements rotation encryption/obfuscation. The default action is similar to rot-13, but it can also rotate over the entire UNIX printable character set.

a Project with All the bells and whistles to allow the average user to fully benefit from HTTP,DNS,FTP,SSH through python, allowing quick and easy deploying of servers without compiling, or installing anything but our favorite language.
