Java Chaotic Random Number Generator - Inspired by chaos theory, the intent of this generator is to produce unseeded, unpredictable numbers. The numbers will not follow a predictable sequence and will not rely on a pseudorandom algorithm.

JCryptor uses the Caesar-cipher to encrypt keystrokes on-the-fly. It can also be used to decrypt an encrypted text easily. Caesar-cipher is a simple encryption algorithm, developed by Julius Caesar, to encrypt his correspondence with Cicero in the ancient world. Therefore it uses a simple character substitution method to replace a given character by another. A keyshift of thirteen is called ROT13. ROT13 can be decrypted by encrypting it again with ROT13. Even today this simple method is used by authorities to protect documents from unintentional reading. --UPDATE-- [25.01.14] Release 1.0 (final) -- Bugfixes [05.05.12] Release 0.2 -- implements polyalphabeticel substitution

JFish is a simple Java implementation of the popular Twofish cryptography algorithm. It allows any application to easily implement powerful encryption, using a single small library and minimal code changes.

JRijndael is a 100% pure Java implementation of the popular Rijndael (aka AES) cryptography algorithm. It's designed to be implemented as easily as possible and features ECB, padding, and a simple API.

JSerpent is an easy to use Java implementation of the powerful Serpent cryptography algorithm. It can be easily implemented into any project, and is complete with ECB, padding, and a simple API.

Java Randomness Test Suite is a gui application to run randomness tests on random stream resource (file or algorithm). Application can be run in command line. Includes general statistical tests, NIST and DIEHARD tests.

The Latin Square Toolbox contains software tools for efficiently generating Latin squares and counting their transversals with various user-configurable options. This open source release aims to help educate folks on Latin squares and their important applications to cryptography. This version contains three tools: 0. Latin Square Generator (LSG) 1. Latin Square Transversal Counter (LSTC) 2. Latin Square Property Checker (LSPC)

A command line interface for encryption and decryption using the NTRU cryptography algorithm. "NTRU is a public key cryptosystem that is considered unbreakable even with quantum computers. Commonly used cryptosystems like RSA or ECC, on the other hand, will be broken if and when quantum computers become available."-NTRU

OhCrypt lets you easily encrypt and decrypt files using some of the most popular algorithms, like AES, Blowfish and Serpent. With OhCrypt, you can secure your data with a password-based encryption algorithm through a clean and simple interface. It demonstrates state of the art of cryptology techniques, such as password hashing and salt. Ohcrypt also features self-extractable and self-destructive encrypted files

A command-line to help encipher and decipher your password based on a simple algorithm. Java version provides GUI.

Java implementation of Shamir's Secret Sharing algorithm as described in Applied Cryptography [as LaGrange Interpolating Polynomial Scheme].

Very simple to use symmetric Java encryption utility. Please write a review. Email me with any questions or problems.

Private-key, symmetrical (same password to encrypt and decode) file encryption with 8-bit to 2147483647-bit (2^3 to 2^31) encryption using my own algorithm and my own extension of MD5 (http://blog.robtoth.net/2009/06/tencryption-computer-programming.html

This package is a modest implementation of a non-alphanumeric encryption algorithm in java. But I'm kinda looking forward to creating a whole gui app implementing most well-known encryption tools, "the paranoid secret-coder special brainkiller"!

XTEA (eXtended Tiny Encryption Algorithm) support for db4o open source object database. XTEA is a block cipher that operates on a 64-bit block size with a 128-bit key. An extremely tiny but very fast encryption algorithm (with cycles less than 32 rounds)

distDES is a Java RMI-based application which manages load balancing on heterogeneous clusters. Development will extend the theoretical initial implementation to include clustered Rainbow Table generation and encryption algorithm collision detection.

compare time of process between rsa and elgamal algorithm used to encryption and digital signature.

jCryptPad stores text informationen hierarchical, e.g. passwords, important texts etc. The data is saved in a encrypted xml file. Encryption is done with the AES algorithm. Additionally a password generator and a text encryption editor is also included.

I did not see a pre-built version of this software on the original developers Github project (https://github.com/gaborbata/jpass), so I am taking it upon myself to compile the releases as they come, so that others don't have to. --Description-- JPass is a simple, small, portable password manager application with strong encryption. It allows you to store user names, passwords, URLs and generic notes in an encrypted file protected by one master password. I will not add the source here, as I will not be keeping it up to date. Just the releases as they are updated on his/her github. If you require the source, or want to compile on your own, here it is: https://github.com/gaborbata/jpass

SJEA version 1.0 - Simple Java Encryption Algorithm. SJEA is a simple command-line binary encryption algorithm (symmetric block cipher) written in JAVA. It uses a password and a byte-vector array to scramble the input file.

Textcrypter is an encryption tool using vigenere cipher algorithm. Vigenere use the same key/password to encrypt and decrypt a file (symmetric key cryptosystem). Result of the encryption process is a ciphertext in hexa number.
