MikroTik WinBox Terminal Client: implementing the terminal protocol

MikroTik WinBox Terminal Client implements RouterOS CLI access over the proprietary WinBox terminal protocol on TCP port 8291. Its Python code handles M2 TLV messages, EC-SRP5 or legacy MD5 authentication and AES-128-CBC terminal traffic. A companion specification records handshake fields, key derivation and message framing.
