PHP functions and classes to add a Domain Key Identified Mail (DKIM RFC 4871) signatures to emails sent by PHP. It is based on the openssl extensions of PHP. It can generate DKIM signature but cannot verify them. Developped and tested on PHP 4.0.

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

This project involves implementing simulations of Enigma machines and the Turing bombe on various parallel-computing systems including multi-processor PCs, Linux clusters, and modern enhanced graphic cards.

Application scans a given textual string in 146 pen on paper possible combinations- horizontal, vertical, diagonal, reverse, join top, join bottom, groups(2/3/4..), edges & in quadrant dimensions of your choice

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 https://github.com/01alekseev/Petoron-P2P-Messenger

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/

Pyton GnuPGInterface is meant to be a filehandle-concentrating Python interface to GnuPG, the GNU Privacy Guard. It has an API similar to the Perl module GnuPG::Interface.

Rinecrypt uses the Gladman implentation of the AES algorithm Rijndael and a SHA256 hash among other things, to encrypt/decrypt a file with a user supplied passsword.

Rockhopper is IPsec/IKEv2-based VPN software for Linux. This software is interoperable with Windows 7, Windows 8 and Windows 10 VPN clients and it provides a handy AJAX-based Web console to manage Secure Virtual Ethernet(LAN), Routing-based VPN, Remote Access VPN and servers protected by IPsec. No kernel modules are needed. The ESP protocol stack is also implemented in user space.

Bash shell scripts to run an OpenSSL Certificate Authority (CA) and issue self-signed HTTPS server certificates (or cert signing requests) for intranets. Scripts: genrootca, genservercert, genusercert, revokecert, csv2usercerts, certificate-mailer.

SecretBox is an open-source, high-safety password manager for Windows/Linux/J2ME devices. You can build the passwords list conveniently in PC side, encrypt it by a master password, and upload to your mobile phone.

A program that encrypts multiple files. It uses new encryption algorithms, such as a Three-Block Feistel chiper, ArchFurry's algorithm and a new hash function. Licensed under the ISC.

Secure Key is an uncrackable security mechanism that minimizes trust given to stored keys, and obfuscates key data in random noise. The Secure Key itself is a hardware device that plugs into your PC (and the server the other end). The key is sent to user

Application which allows encrypting text. It is encrypted using own libraries. I think it is a very strong way to encrypt, specially if the text has more than 1 KB. The application reads encrypted bytes from disk, and writes encyrpted bytes to disk, so it never is saved in the hard disk decrypted. JDK-17 compatibility

Ncurses based tool for easily deploying IPsec tunnels using FreeSWAN (Linux only) Easy to configure a tunnel, simple options, user friendly interface

Open source enterprise collaborative password manager and file storage. Download and install on your own servers or let us prepare your installation on dedicated server. Store and share your sensitive data safely and manage users who are allowed to access the information. Vaultier is based on advanced security technology (RSA over AES). All data stored in Vaultier databases are encrypted. Only authorized users with valid keys can read them. Encryption keys always stay on client machines. Vaultier is not an online service where all clients and users share the same database. What you always get is a standalone installation with your own database. Vaultier offers you a free opensource Community version and paid Enterprise edition which comes with more features and services in three subscription plans.

An electronic votingsystem – Verifiable E-Voting (VEV) – with underlying protocol to help secure the election process from malicious practices at the same time as allowing voters and candidates to verify the correctness of their votes.

Vigen is a Unicode UTF-8 multi-pass rotation encryption system based on the classic Tableau de Vigenère. Vigen is an experiment using this particular cypher, intended for those who are interesting in building their own encryption tables. Vigen can generate exceedingly strong rotation cyphers that are probably unbreakable without the given keys and tables. Vigen might even generate military grade cyphers, although I make no claim as to the security of the cypher. Vigen is for encrypting UTF-8 TEXT files; it is not intended for encrypting binary files. Vigen is not a private/public key encryption system such as PGP (at least, not yet).

X Test - An 802.1x Supplicant test tool for IP Phone / VoIP Infrastructure environments.

An application to provide a worldwide mobile secure/confidential payment system over the internet and other kinds of insecure/unreliable networks

alr-encrypt has moved to http://sourceforge.net/projects/encrypt

crax is a wordlist based md5/sha1 tester, written in c++ for Linux and other *nix based systems.

Allows to transparently encrypt repository contents with AES 256. The main advantage is that no additional software needed to be installed in untrusted location. Files are automatically encrypted on the fly when doing git push from trusted location.

haveged is a daemon that feeds entropy into the linux /dev/random pool using a random number generator based upon the HArdware Volatile Entropy Gathering and Expansion algorithm.
