This PR simplifies our stream cipher implementation quite a bit and adds ZK functionality to its public API. This is the first step needed to support #330 and it also provides the changes needed to bump mpz version to support #379

Changes

  • Modified AES-CTR circuit to only compute the encrypted counter block, without directly applying the input text.
  • Removed padding of the input text, this is no longer needed as we apply the keystream to the input text using a dynamically generated XOR circuit.
  • Added the prove_plaintext and verify_plaintext methods
  • General code clean up, refactoring out complexity
