Visualize the Triple Data Encryption Standard (3DES) algorithm (Encrypt-Decrypt-Encrypt mode).
Note: This shows the main stages. The 16 rounds within each DES operation are treated as a single step for clarity.
Inputs
Visualization Steps
Step 1: Initial Permutation (IP)
The 64-bit plaintext is permuted according to the IP table.
Plaintext: IP Output:
Step 2: DES Encrypt with Key 1 (K1)
The result of IP is encrypted using the standard DES algorithm with Key 1 (K1).
Input: Key 1: DES Encrypt(K1) Output:
Step 3: DES Decrypt with Key 2 (K2)
The result from the previous step is decrypted using the standard DES algorithm with Key 2 (K2).
Input: Key 2: DES Decrypt(K2) Output:
Step 4: DES Encrypt with Key 3 (K3)
The result from the decryption step is encrypted again using the standard DES algorithm with Key 3 (K3).
Input: Key 3: DES Encrypt(K3) Output:
Step 5: Final Permutation (IP-1)
The result of the final DES encryption is permuted according to the inverse IP table (IP-1) to produce the ciphertext.
