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.

Encrypt and decrypt text with my own encryption algorithm. (Executable included)

CryptoHelper is a Java program designed to aid in the decryption of classical ciphers, ie pre WWII ciphers. It brings together tools like frequency analysis, friedman tests, enciphering/deciphering for several clasical ciphers, and brute force algorithm

CryptoServer is the daemon for handling Sign-Verify, Encryption-Dencryption, Envelop-Openenvelop based on OpenSSL including the SEED symmetric algorithm (Korean Standard Symmetric Algorithm). It's interface is just tcp/ip socket and very easy to handle

Cryptomni is a program which can encrypt and decrypt files using the one-time pad cipher. If a key is truly random, kept secret, and never reused, this encryption algorithm can be proven to be unbreakable.

Cypher is an encryption program that uses the AES (Rijndael) algorithm to encrypt and decrypt files. You can use Cypher to protect sensitive data from unwanted access.

This Java project is an attempt to crack the key in a DES encryption algorithm. The plaintext and the cyphertext are known. The purpose is to crack the 64-bit key with 3 rounds instead of 16. This project checks all 2^64 possible keys. Therefore, it takes a long time to find the correct key.

A very powerful and secure encryption supporting multilevel algorithm hierarchy encryption(bit level),supports infinite length keys and equation creation utility(secondary key) for the utmost security.Support for multiple algorithms.All OS support(ja

A Visual Basic implementation of Bruce Schneier's Solitaire Encryption Algorithm that encrypts plain text by means of a deck of ordinary playing cards.

DecodeBase64 does exactly what the title says: it decodes strings encoded with the Base64 algorithm. Source code is provided in both Java and C++.

A encryption library for C++ "DEL-X" that uses a 3d encryption algorithm. It can work with any key size from 8bit- 4096bit with a 512 byte block size.

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.

DrCrypt, based on basic xor(exclusive or) encryption which is designed to be fast and reliable. Also DrCrypt supports 3 platform.(Java, .NET, Win32)

A cross platform implementation of ECDSA (elliptic curve digital signature algorithm) interface to the aSuretee Token.

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

ES-E is a fully downloaded encryption algorithm that you can use for your WebServer or use it for your programs (by grabbing the output off the webpage). Check the Files page for the latest build.

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.

A library written in Java and C# for crypt,encrypt and generate key pairs using the ElGamal algorithm.

This is free Java desktop application to keep your note in safe from others using the Encrypting Decrypting symmetric key algorithm, it's easy to transfer your note form source to another in confidential manner.

Enfomi is a cross-platform standalone password-based encryption/decryption program that supports 27 algorithm variants (including AES 256bit). Archives can be self-decrypting, thus making it perfect for mobile applications.

Enigma3 is a substitution-based encryption algorithm that can be applied to binary or text data and results in far greater security than traditional encryption. An electronic dictionary of words is employed and numeric codes are then assigned to each word within the dictionary. Communications are coded as a set of numeric codes which can then only be translated back into the original message by using the original coded dictionary. This is not an encryption method in the commonly accepted sense as it is not based purely upon and cannot be compromised purely by mathematical means.

This is an encrypter. It can be used to encrypt confidential information. Prefect for sending file over the Internet without others knowing the content of the file. The encryption algorithm used in this software is similar to the one that's used by espionage.

· A free chat server coded in java. · Supports secure connections via the Diffie-Hellman-Algorithm. · One java chat client available. · Other clients in production.

My first attempt at a one-way hashing class/algoritm, built as a python class. It produces variable length hash from a message block of the size you want. The resulting hash will be ~2x the message block in size, and should provide for at least as many bits of security as the block itself. I updated this, with a different hash than original, since I found a potential collision on some blocks, not but specific to that challenge. To further correct this, I modified the padding when it's less than the block size. I hold no guarantee of the security of this algorithm, USE AT YOUR OWN RISK. I have had no 3rd party analysis done on the algorithm to date, but research is welcome, and a challenge is even provided in CHALLENGE.txt.
