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
