Description of Figure The KeyAgreement Class

This figure is divided into halves by a dashed line. The top half is labeled Alice, and the bottom half is labeled Bob. The figure consists of boxes labeled as follows:

• These boxes are in Alice's half:
  • Key: This box contains a box labeled Alice's Private
  • Key: This box contains a box labeled Bob's Public
  • Key Agreement (DH)
  • Bytes: This box has another label, Bytes
• These boxes are in Bob's half:
  • Key: This box contains a box labeled Bob's Private
  • Key: This box contains a box labeled Alice's Public
  • Key Agreement (DH)
  • Bytes: This box has another label, Bytes

Labeled arrows connect these boxes:

• These arrows are in Alice's half:
  • init(): From Alice's Private Key to Key Agreement (DH)
  • doPhase(): From Bob's Public Key to Key Agreement (DH)
  • generateSecret(): From Key Agreement (DH) to Bytes
• These arrows are in Bob's half:
  • init(): From Bob's Private Key to Key Agreement (DH)
  • doPhase(): From Alice's Public Key to Key Agreement (DH)
  • generateSecret(): From Key Agreement (DH) to Bytes

A double-headed arrow joins the Bytes boxes in Alice's and Bob's halves. This arrow is labeled "Should be the same."

• init(): From key length to Key Generator (AES)
• init(): From AlgorithmParameterSpec to Key Generator (AES)
• generateKey(): From Key Generator (AES) to Secret Pair
