Encryption/Decryption demonstration app using the S-DES algorithm
...The GUI pops up that allows entering a 10-bit encryption/decryption key in binary (0, 1 digits) and the plaintext/ciphertext in the same form (8-bit). Executing the algorithm, decription of the encoding/decoding functionality is provided in the three main text boxes.
vCrypto can be used to have secret text based conversations. Use this application to Encode your message and then send the encoded message to your desired recepient.
Also, for enhanced security one can encode the message into a file which will be encrypted with a user provided password.
Send that file to your desired recepient and then use this application to decrypt and decode the message from the file.
