Decryption Messages

Message interface

type DecryptionMsg :=
  | DecryptRequest {data : Ciphertext}
  | DecryptResponse {
      data : Plaintext;
      err : Option String
    };

DecryptRequest message

DecryptRequest

DecryptRequest {
  data : Ciphertext
}

A DecryptRequest instructs a decryption engine instance to decrypt data as the internal identity corresponding to that engine instance.

• data: The encrypted ciphertext to decrypt.

DecryptResponse message

DecryptResponse

DecryptResponse {
  data : Plaintext;
  err : Option String
}

A DecryptResponse contains the data decrypted by a decryption engine instance in response to a DecryptRequest.

• data: The decrypted data.
• err: An error message if decryption failed.
