The OpenSSL shell/batch script collection offers insight in how to setup a hierarchical PKI structure consisting of a Root CA, several sub CA's and end entity digital certificates. The scripts are available for unix and windows.

Secrets for Android is an app that allows you to securely store and manage passwords and secrets on your Android device. PCSecrets is an application that provides similar facilities for a PC. PCSecrets Sync is an Android app that provides a synchronization capability between the two. It makes use of the new synchronization interface introduced in Secrets for Android (SfA) 2.4. The app is essentially a service and has no direct user interaction (no user interface). The app can be installed from Google Play or the .apk file can be downloaded from here. Secrets for Android is available on Google Play. PCSecrets is available on SourceForge. Click on the web site link below for full documentation.

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 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

A client for the passcracking.com online database ob MD5 and SHA1 Hashes. It allows to generate MD5 and SHA1-Hashes from passwords and querying the database to get the password for a given hash.

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.

The Password Auditing Project will be a compilation of other, previously released password auditing programs, in such a fashion as to reap the best benefits of each portion. Pulling innovations from John the Ripper, Lepton, Rainbow Tables, and more.

Password Generator is Mac OS X application which generates random passwords based upon options chosen by the user.

Petoron P2P Messenger (P-P2P-M) Architecture: Pure P2P - no servers, no databases Key storage: Keys generated in memory, never stored, erased after use Metadata: Only IP and port exist during the session - everything else is encrypted & obfuscated Encryption: PQS v1.2 - PBKDF2-HMAC-SHA256 (200k), BLAKE2s-MAC, custom stream cipher + fake padding Authentication: BLAKE2s-MAC (16 bytes) - instant failure on any data change Packet obfuscation: --stealth mode - padding, hidden structures Connection: Direct peer-to-peer only Anonymity: No accounts, logins, or phone numbers Third-party access: Impossible without physical access to both peers during session History: No storage — all in RAM, wiped on close Message size: Limited only by RAM & MTU — no artificial limits External dependencies: None DPI/blocking resistance: Harder to detect, can be masked Autonomy: Fully offline until peers connect 26.01.26 Add pqs_chat_tor.py github.com/01alekseev/Petoron-P2P-Messenger

PetoronHash2 (PH2) is a standalone ARX-based sponge construction that combines: A 4096-bit internal permutation core A sponge/duplex architecture with explicit capacity separation An extendable-output function (XOF) Memory-hard (HARD) and burn (BURN) modes A structured tagged absorb scheme A parameterized architecture suitable for hashing, KDF, and stress-oriented derivation PH2 is designed as a wide-state cryptographic primitive with explicit domain separation and configurable output length. https://github.com/01alekseev/PetoronHash2 Petoron | Ivan Alekseev | MIT license

platform independent solution to encrypt files on a portable Device. Files will be encrypted with TripleDES and hold in an XML-File. No local Installation needed.

I wrote this in 1997. Right now I have the basic code up. I have it in c++ too but I have yet to upload it. This program is good for small files but does not handle large files very well. It creates a binary key to increase the entropy of your file. It can use the key to reverse the entropy of your file. So, it encrypts and de-crypts.

Project Naranja will uses Padlock Security of VIA EPIA mini-ITX motherboards in order to provide a toolkit to set up and use encrypted filesystems with Linux. NOTE: Files are now hosted at Google Code: http://code.google.com/p/naranja/

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 ---

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.

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.

The QR-CERT software is a specialized package of applications dedicated for the development of a Public Key Infrastructure system as well as the cards personalization and management system. The software contains a number of functional modules, enabling a flexible selection of functionalities for implementation. The software is dedicated for large organizations and corporate environments, with a PKI infrastructure and microprocessor cards. The QR-CERT is a solution both for the companies which plan to build their own PKI infrastructure and entities planning to provide services in this respect. This software enables the implementation of advanced security mechanisms, such as: secure e-mail (S/MIME), electronic signature (PKCS#7, XAdES), network transmission protection (IPSEC, SSL/TLS) and strong authentication for service portals (HTTPS) or strong authentication of users for the Windows ActiveDirectory domain.

This library provides two operations: one to wrap key data, and another to unwrap the key data. This code also includes a fairly comprehensive unit test library which ensures the implementation is verified against the vectors provided in RFC 3394.

RG-Safe uses the Cryptlib library to keep all your information "safe". You can import files into your SAFE. From there you can securly view it, reencrypt it, export it or email it securly to someone on your keyring. You can sign/check files & also comat

This is a ROXster. A program that encrypts files and text with an algorithm based on XOR. You can use it to encrypt your files or text fast and easy. Enjoy!
