Message interface¶

`MsgDecryptionRequest RequestDecryption`¶

type RequestDecryption := mkRequestDecryption@{data : Ciphertext};

A RequestDecryption instructs a decryption engine instance to decrypt data.

Arguments

data:: The encrypted ciphertext to decrypt.

`MsgDecryptionResponse ResponseDecryption`¶

type ResponseDecryption :=
  mkResponseDecryption@{
    data : Plaintext;
    err : Option String;
  };

A ResponseDecryption contains the data decrypted by a decryption engine instance in response to a RequestDecryption.

Arguments

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

`DecryptionMsg`¶

type DecryptionMsg :=
  | MsgDecryptionRequest RequestDecryption
  | MsgDecryptionResponse ResponseDecryption;
