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

This is an experimental program that encrypt/decrypt/divide/join files. This program uses a new algorithm made by me, this algorithm is experimental and I working on it, every day this algoritm will be better.

We developed a classic solution that reflects the very nature of quantum mechanics in whole, ultimately demonstrating the raw power of numbers. We developed a truly irreversible one way algorithm which, when applied to information, both encrypts and decrypts it. That is to say that the algorithm which encrypts the information works in the same direction as the algorithm that decrypts it. This in itself is the very nature of quantum mechanics - "forward only". Through a quantum-entanglement-like operation, we created very robust encryption methodology which will secure information for some time to come through sheer numbers and flexibility. With 2^65536 possible keys a brute force attack on a key is simply infeasible. The full version, due to release March 11, 2013 will allow password protection which helps protect your information by forcing the impostor to not only produce the 65536 bit key, but have your password as well and allows for individual passwords for individual files.

It is a fine tool to encrypt your data.It uses a dinamic algorithm and a nice interface.It`s easy to use and helpful.

In distributed cryptosystem a secret key is distributed among the participants of the system, in the way that only a group of some authorized users can perform any actions related to the secret key. A secret key is used to encrypt a session key, create a digital signature and to certify public keys. The system uses symetric encryption algorithm with a session key to encrypt messages. Shoup’s threshold signature scheme has been used for cooperative signing and also for cooperative decryption.

ENIGMA 2000 is a symmetric cryptographic algorithm developed in C++ for Windows, to encrypt any file. It is not optimized for speed processing but it is extremly reliable. Tests state that a huge input file just with zeros, will return an output file whose frequency analysis is white noise. It uses six phases to encrypt any file and the phases sequence depends on the password. On phase 5, it uses the Rubik's cube paradigm to encrypt the data. It's extremly reliable and the password varies between 8 and 16 characters. The execution syntax is: coder.exe [file to encode] [password (min 8 char, max 16)] [mode ('c'oder 'd'ecoder)] Enjoy it

This simple encryption program, allows you to virtually encrypt all documents and even decrypt them back using the secure XOR encryption algorithm. This program is designed for beginners who know little about encryption.

The hash latch generates keys in a manner similar to how some cryptocurrencies are mined. It takes a string and brute-forces a prefix for it so that the hash of the string with the prefix has a certain number of leading zeroes. But that alone would've been too easy to hack. To prevent an attacker from forging the keys by generating a new prefix: the hash latch doesn't output the keys in the plaintext. Instead, it encrypts the key and outputs the ciphertext. That means that instead of giving you the actual key, it gives you a safe containing the key. This approach allows the hash latch to protect itself from forged keys and also enables you to put the same key into multiple safes without the recipients of these safes knowing they have the same key (even if they compare their ciphertexts). Moreover, the hash latch verifies the integrity of a key after decrypting it (just in case). You can read the tutorial about it on Instructables: https://www.instructables.com/Hash-Latch/

JDS is a powerful tool for data protection. Documents are encrypted using a special algorithm. The data encryption algorithm is constantly updated to improve security. The program also provides other functions. Such as sending a file to a vault with password access, fast text encryption in 3 types, and much more. The program is easy to use and does not require special knowledge. The standard version has 2 languages (Russian and English) and 9 themes. You can download the language and theme pack separately.
