DES-Rotem
DES attempt to crack code with 3 rounds
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. -

TEAENCRYPTION
A TEA encryption with GUI for 32-bit 64-bit works only on windows.
A algorithm encryption based on TEA (Tiny encryption Algorithm) that will help the user to encrypt his text files and decrypt whenever the user wants as long as he uses the same key.It is simple to use but doesnt work with really really long text files.Will implement mac and other OS in the future. -

Ncrypt
Text and image encryption and decryption software
This software provides a mean for users to encrypt and decrypt data in the form of text and images. The program follows a basic encryption algorithm that relies on mathematical properties of matrices, such as row operations, matrix multiplication, and invertible matrices . This program works by allowing the user to input a key in the form of a matrix, on which the program bases the encryption. The program then performs the encryption. The software only works in the scope of text files with a maximum of 150 characters, and image files with a maximum size of 128 x 128. -

jPass - Cross-Platform Password Manager
Compiled into a single .jar file. Tiny Password Manager. Portable
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... -

NCrypted
NCrypted - simple file encryption software with GPU support
NCrypted is a simple file encryption software. It is implemented on top of AES 128-bit algorithm. This software was designed to be as simple as possible, so you won't find any fancy, flashy gui elements or complicated advanced options. You can also use it directly from command line. NCrypted can automatically detect and take advantage of your NVidia graphics card to speed up the file processing. -

ImpraStorage
ImpraStorage provided a private imap access to store large files
...Each part also contains random noise data (lenght depends on a crypt key) to ensure privacy and exclude easy merge without the corresponding key. An index of files stored is encrypt (with the symmetric-key algorithm Kirmah) and regularly updated. Once decrypt, it permit to perform search on the server and download each part. transfert process is transparent. Just vizualize locally the index of stored files and simply select files to download or upload. ImpraStorage automatically launch the parts to download, then merge parts in the appropriate way to rebuild the original file. ... -

Fileprivacy
Fileprivacy easily encrypts your files
...#######BETA 2####### Bugfix - Beta 1 stopped working if filename was too short or long - added .exe file ####### NOTE ####### This is an early beta implying there are some issues left. The Keygenerator stops working if you change the algorithm after setting the keylength. It has to be restarted for further use. Because there are no start scripts, yet, you have to start Fileprivacy from console by typing: java -jar Fileprivacy-1.0_<version>.jar ####### ALSO NOTE ####### The author of this software is not responsible for the safety of your data. There is no guarantee that one or more of the implemented algorithms cannot be compromised. -

JCryptor
JCryptor is an encrypting tool based on the Caesar-cipher.
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. ... -
