    Encrypt Your Text documents with XOR encryption

    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....

    SecuXabber

    SecuXabber

    A secure Jabber-client for Android using strong encryption

    SecuXabber is a secure Jabber-client for Android that bases on Xabber and uses a strong, asymmetric enryption that works on top of the XMPP protocol. A key pair is generated on application start-up. Users can send their public key to other SecuXabber users via Bluetooth. This ensures the origin of the public key because people do a face-to-face check during key exchange. After the keys are imported by both users, all communication between them is done fully encrpyted using a strong 4096 bit...

    U-Tranz

    U-Tranz

    UDP based secure file transfer application written in JAVA.

    U-Tranz is a free application developed on the characteristics of UDP allows the transmission of unlimited file size. Most of the applications based on UDP restrict file sharing upto 64kb which makes transmission less efficient on large files. Along with the tremendous increase in file size, certain features like implementation of Government Standard Security Algorithms (AES-256*/RSA-2048 and SHA-512) have been added to this application for secure sharing of huge files across different...

    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...

    chaOS41

    A cryptocurrency like Bitcoin improved upon with reality binding.

    There is a reason this project holds no code. chaOS41 is a cryptocurrency with reality binding. A given value of money was paid for a surface area the size of a flower pot. It was out of proportion. The chaoOS41 currency corrects that. It binds its value to reality. Its unit value is a ratio between money and land area.. When that ratio normalizes, the currency becomes available to the public. 1 more developer is wanted. For that you need inside access, which means...

    Vigenere Dictionary Attack

    Vigenere brute force / dictionary cracking tool

    This is a tool that uses a combination between a brute force and dictionary attack on a Vigenere cipher. At present, keys are generated using brute force (will soon try passwords generated from a dictionary first). Each key is then used to decode the encoded message input. The output is analysed and then put into a ranking table. Outputs will be ranked on a variety of factors (at present, only number of dictionary words in output are counted). For the future: Better key generation,...
