module TD::Types
  # Represents a secret chat.
  #
  # @attr id [Integer] Secret chat identifier.
  # @attr user_id [Integer] Identifier of the chat partner.
  # @attr state [TD::Types::SecretChatState] State of the secret chat.
  # @attr is_outbound [Boolean] True, if the chat was created by the current user; otherwise false.
  # @attr ttl [Integer] Current message Time To Live setting (self-destruct timer) for the chat, in seconds.
  # @attr key_hash [String] Hash of the currently used key for comparison with the hash of the chat partner's key.
  #   This is a string of 36 bytes, which must be used to make a 12x12 square image with a color depth of 4.
  #   The first 16 bytes should be used to make a central 8x8 square, while the remaining 20 bytes should be used to
  #   construct a 2-pixel-wide border around that square.
  #   Alternatively, the first 32 bytes of the hash can be converted to the hexadecimal format and printed as 32
  #   2-digit hex numbers.
  # @attr layer [Integer] Secret chat layer; determines features supported by the other client.
  #   Video notes are supported if the layer >= 66.
