encode_to_light_plaintext

Engine.encode_to_light_plaintext(message, level)
Encodes a message into a light plaintext format for multiplication. The maximum size that can be encoded at once is determined by Engine.slot_count. If the message length exceeds this size, an error is raised. If it is smaller, the message is padded with zeros during encoding. The recommended range of values to encode is [-1, 1].
  • Input:
    • message: A Python list or numpy array. Data types supported include int, double, and complex double.
    • level: optional
      • Should be set to the level of the ciphertext that the light plaintext will be multiplied to.
      • The level should be an integer greater than or equal to 1.
  • Output:
    • LightPlaintext

Warning

  • The matrix form does not yet support this operation.
