The Data Encryption Standard (DES)
Chooses the key \( K \).
Encrypts the plaintext blocks \( x \):
Enter the message (or integer) that Alice wants to send encrypted to Bob:
Press Enter to generate the parameters. You can use the Left and Right arrow keys to navigate between steps.
Before Alice can encrypt the message \( m \), she must first convert each letter into its corresponding ASCII value, and then convert each ASCII value into its binary representation.
Receives the key \( K \).
Receives the ciphertext blocks \( y \).
Decrypts the ciphertext blocks \( y \):
