Vote for CryptoCrat
CryptoCrat 2004 encrypts multiple files into one single solid encrypted archive using encryption algorithms including AES. It transforms files' data into gabberish undecipherable by others. If the scrambling of the data is done properly, the original file can only be unscrambled and read by someone who knows the secret key i.e. the code used to encrypt the file. Interface like Windows Explorer. Secure files deletion.
