Naeon secures data in untrusted off-site storage through a layered approach: files are compressed, then AES-256 encrypted with a randomly generated 128-character passphrase yielding approximately 762 bits of entropy — far beyond the reach of both classical and quantum brute-force attacks. The ciphertext is obfuscated by prepending and appending random byte blocks, making the result unidentifiable as an encrypted file. The payload is then sharded into one private chunk — holding the encryption key and part of the data — and multiple equal-sized public chunks, each renamed to its SHA-512 hash and given a uniform timestamp to prevent metadata inference. A private filename conversion table preserves the concatenation order needed for restoration. Together these measures guarantee confidentiality, integrity, and availability regardless of storage provider trustworthiness. Threshold Key Sharing extends this further by splitting the private key, eliminating the single point of failure.

Self contained and completely portable binary encrypts text for secure email, messaging, irc use, etc., ideal for USB flash drives. AES-128/192/256 (ecb/cbc), Blowfish (ecb/cbc), DES / TripleDES (ecb/cbc/ofb/cfb), or RC4. Linux and Windows binaries. I don't make cute interfaces, it just works. https://codeberg.org/BloodFeastMan/pte I would also recommend FTC, encrypts both files and text using the same interface as PTE, and a separate encryption and hashing engine I wrote in Crystal, and is much faster than PTE: https://sourceforge.net/projects/ft-crypt/

Rose Crypt provides users with a simplistic application that can be used for encrypting files in your computer using a custom passphrase. With its minimal design, Rose Crypt can be used by both advanced and beginner users. Once the encryption process is finished, you can access the newly created file from the location you previously selected.

An extremely versatile neural net. Hopefully.

This is a tool that uses a combination between a brute force and dictionary attack on a Vigenere cipher. At present, keys are generated using brute force (will soon try passwords generated from a dictionary first). Each key is then used to decode the encoded message input. The output is analysed and then put into a ranking table. Outputs will be ranked on a variety of factors (at present, only number of dictionary words in output are counted). For the future: Better key generation, trying combinations of dictionary words with numbers. If that fails, brute force will be used. For all attempts of the dictionary attack, only keys within the known key length range will be generated. Better ranking system and analysis of possible decoded messages. Note: The version currently released, I made in an evening! It is nowhere near ready for release but is a fun project to think about and I need more ideas for improvements mentioned above. Discuss possible solutions and ideas!

This software provides an easy graphical way to encrypt your text documents from source code , text files ,scripts even jpeg files .It is a enhanced version of my earlier project https://sourceforge.net/p/xorencrypt which used win32 GUI . This is a demonstration of working of XOR encryption which was used by Germans in World War II (http://en.wikipedia.org/wiki/Lorenz_cipher) . Besides from XOR'ing the message with password after every encryption the key changes pseudorandomly. The password you provide is hashed ( SHA256 ) and saved into the encrypted file to check if the password provided is correct.This algorithm has limitations in general more the numbers of relative characters in the password to plaintext more secure will be the encryption. XOR encrypt has a 3.5 of 5 editors rating from softpedia http://www.softpedia.com/get/Security/Encrypting/XOR-Encrypt.shtml

jHashCalc is a GPL implementation of the popular hashing utility "HashCalc" from SlavaSoft. jHashCalc is written in Java language, and uses the GNU Crypto API to perform the algorithms' computing.

ECTP - Encrypted Compressed Transfer Protocol This protocol is similar to HTTP but with commands and features like FTP. The main features are security and compression abilities and the consequent use of one perisistant connection.

JHide is simple steganography tool aimed to demonstrate basic steganography techniques.

This is an IRCd based off of bahamut-1.4.35 that includes IPv6 and SSL support. We will be adding more advanced features as well such as host hiding (+x), IRC operator levels, halfops support, more channel modes, etc.

Command-line strong encryption tools including: triple cascaded encryptor, multiple hash calculator and multiple block cipher encryptor. Supports AES, Serpent, Twofish, SHA-512, RIPEMD-160, MD5 and other algorithms.

SSHDOS is a DOS port of SSH, SCP, SFTP and Telnet clients. Needs a packet driver (or a PPP driver for dialup connection) only. There are two separate packages for SSH1 and for SSH2.

A simple but powerful cross-platform utility for managing and accessing your most secret data. It stores passwords and whole files, so it can literally store any information you want to keep secret. Access your most-used passwords/URLs right out of a desktop tray icon. For advanced users, it includes a separate utility called Grypto-Transforms, which has a universal hash calculator with all the major hash functions, generic encrypt/decrypt functions and a base64/hex converter. Although the interface is simple and intuitive, the security is top-notch. It uses AES with CCM to secure and authenticate the data.

Crypto Notepad Plus is a free text editor with advanced encryption features. Also you can generate code snippets in various programming languages. Its use is governed by the GPL (GNU General Public License). Tested on Windows operating systems, from version 7 to 11.

A simple working implementation of 64-bit DES encryption/decryption alogrithm in C++. Could act as guide to undestanding the algorithm. Its buggy so help me out :-)

DavUtils is a collection of easy to use WebDAV client tools. The built-in client-side encryption allows you to encrypt and decrypt files on the fly with AES. Currently two command line tools are available: dav is a multipurpose WebDAV client that can be used like the standard unix tools ls, mkdir and rm. The other tool is dav-sync that can synchronize local files with a WebDAV server. It is very flexible and configurable and has advanced data safety features to prevent data loss. The integrated client-side AES encryption makes it secure to use public clouds.
