    Bigram Table Generator

    Bigram Table Generator

    A program to generate random reciprocal bigram tables

    A command-line program to encrypt/decrypt a message using a random reciprocal bigram table and write a bigram table to a text file. Executing the program without any command-line arguments starts bigram in message encryption/decryption mode. The program prompts for a password or passphrase and a message to encrypt/ decrypt. After the message is entered the ciphertext is displayed. Executing the program with command-line arguments causes bigram to generate a random bigram table to...

    innocence-java

    Replace text with POS equivalent text, in a reversible fashion.

    Program takes (currently) english text sentences, and replaces each word in a given sentence with another word having the same Part of Speach (POS) tag. This creates a new sentence containing none of the original words. This new sentence can then be transmitted to a remote user, and using the same software, "de-crypted" into yielding the original sentence. The software relies on having a known "seed" value for the random number generator, which is known only by the sender and...

    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...
