Description of Figure The Cipher Class

Link to figure The Cipher Class

This figure consists of boxes labeled as follows:

Key: Contains a box labeled Secret Key
Plaintext
These two boxes are attached to each other:
- Cipher (AES): Box 1 of 2
- Encrypt
Algorithm Parameters
Ciphertext
These two boxes are attached to each other:
- Cipher (AES): Box 2 of 2
- Decrypt
Plaintext

Labeled arrows connect these boxes:

update(): From Plaintext to the Cipher (AES) #1
doFinal(): From Plaintext to Encrypt
update(): From Ciphertext to the Cipher (AES) #2
doFinal(): From Ciphertext to Decrypt

Unlabeled arrows connect these boxes:

From Key to the Cipher (AES) #1 and Cipher (AES) #2 (the arrow branches)
From Cipher (AES) #1 to Algorithm Parameters
From Algorithm Parameters to the Cipher (AES) compartment of the Decrypt box
From Cipher (AES) #2 to Plaintext
From Decrypt to Plaintext
