TableCrypt is a file encryption utility. The major difference with most file encryptors is that this program uses a generated table in combination with a password to encrypt a file. This way you need 2 variables to decrypt the file. This is how it works: Generate a 10kb table file and enter a password. The password is used to pick bytes from the table file which in their turn are used to encrypt the bytes of the inputfile with XOR encryption.
