This package implements the FF1, FF3, and FFX algorithms and the A2 and A10 parameter sets for format-preserving encryption. The FF1 and FF3 methods for format-preserving encryption are implementations of NIST Special Publication 800-38G, Recommendation for Block Cipher Modes of Operation: Methods for Format-Preserving Encryption. The FFX algorithm and A2 and A10 parameter sets are implementations of "The FFX Mode of Operation for Format-Preserving Encryption," by Mihir Bellare, Phillip Rogaway, and Terence Spies. For more information see the README.txt and package-info.java files in the source.

A very simple file encryption tool. Release 1 is a text editor that saves encrypted files. Release 1.1 will include the ability to convert any file, even binary, to a GEF (Gulosh Encrypted File). Release 2.0 brings the strong encryption into play.

HTTPBrute is used to calculate HTTP Digest Access Authentication as per RFC 2617. The tool will be able to perform brute force attacks to retrieve a lost password for a given Authentication response. MD5 is the only hashing algorithm implemented.

Simple Encrypted chat application built with Java. It uses AES-256 bit block cipher algorithm.

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.

A Java program to encrypt files and make them relatively safe for transfers across networks. Currently just in commandline form, but an application is in the works.

I have packaged the Java encryption library with a wrapper used to make saving and loading files in Java easier. I have also included the source for a command line application to encrypt a String and save it to a text file. The source for AESEncryption was actually written by "erickson" from Stack Overflow. The original post can be found here: http://stackoverflow.com/questions/992019/java-256-bit-aes-password-based-encryption/992413#992413

ROT-13 Encryptor/Decryptor. More functionality will be added as different updates are released.

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.

It's a new, free distribution encryption software that provides Dropbox users with additional security for their sensitive information. Encrypt and securely share your files with other KonEncriptación users via Dropbox. KonEncriptación is fully integrated with Dropbox and is easy to use, thus allowing you to exploit all its features from the start.

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)

Meergoose is a multi-use social suite of applications that allows users to setup a portal on their personal computing platform that encrypts and stores files locally and synchronizes encrypted files with a secure cloud. MeerCrypt is a component of Meergoose and is opensource. The vision is simple: Encrypt Locally. Share Remotely. YOU remain in control of your security, your keys, your data.

The Moonbounce API is a set of high level objects that encapsulate pieces of the Bouncycastle lightweight crypto API. Moonbounce significantly simplifies RSA key generation, signing, encryption/decryption and verification of both byte arrays and files.

Novel Insight Inner Circle is a message and file encryption tool for Windows. The software is developed in Java and requires 64bit Java JRE. The encryption uses AES-256 twice so it is harder to crack than the industry standard pure AES 256bit implementation (theoretical key size is 512 bit). The software writes encrypted data in ASCII text format which can be cut'n'pasted to messaging apps or to emails and back to Inner Circle when decrypting data. IMPORTANT: The software requires new OpenJDK 16 (Not Oracle's J2RE 1.8) to run. Install, for example, AdoptOpenJDK for Windows. NOTE: By using encryption twice the implementation is (in theory) vulnerable to Meet-In-The-Middle attack reducing key size to 256bit but the attack still requires 2^256 bytes of memory making it impossible in practice.

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

Transparent file encryption performs real-time I/O encryption and decryption of the files in any block data with 16 bytes. The encryption uses a 256 bits symmetric key to encrypt or decrypt the data with AES encryption algorithm. Auto file encryption protects data "at rest", meaning the transparent data and files encryption. It provides the ability to comply with policies which can be applied by users, processes and file type. This allows only authorized users and processes to access the encrypted files, unauthorized users and processes can’t access the encrypted files. The Auto FileCrypt Tool was developed with EaseFilter Encryption Filter Driver(EEFD) SDK, a file level encryption filter driver. Run the auto file encryption service with administrator permission, add the managed folders as encryption folder, when the files were added to the managed folder, the files will be encrypted automatically, when files were read, the data will be decrypted in memory automatically.

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

Password Keeper: Password Keeper will be a program that lets you put all of your passwords in one file and encrypt it easily instead of using a flat file.

Simple Encoder/Decoder, written in the .net framework. It is basicly an encryption program which supports serveral encryption methods. It can encode or decode texts in the forms of files or just plain text written directly in the program.

A plattform independent encryption-tool with a simple user interface (swing/java). It uses 'Password Based Encryption' (PBE) to encrypt and/or decrpyt files on the filesystem. Encryted files will also be compressed using the zip-format.
