End-to-end encryption method and device for instant messaging data, electronic equipment and medium

The invention provides an end-to-end encryption method and device for instant messaging data, electronic equipment and a medium. The method comprises the following steps: generating a floating window corresponding to an instant messaging window displayed on a terminal display screen; receiving instant messaging data input by a user in a floating input box of the floating window; in response to a sending instruction for the instant messaging data in the suspension input box, encrypting the instant messaging data to obtain ciphertext data; and sending the ciphertext data to a receiving end through an instant messaging tool corresponding to the instant messaging window. According to the scheme, end-to-end encryption can be performed on the instant messaging data, so that the instant messaging data can be effectively protected when facing attackers including instant messaging operators. 本发明提供了一种即时通信数据的端到端加密方法、装置、电子设备及介质，其中方法包括：生成与终端显示屏上显示的即时通信窗口相对应的悬浮窗口；在所述悬浮窗口的悬浮输入框中接收用户输入的即时通信数据；响应于对所述悬浮输入框中所述即时通信数据的发送指令，对所述即时通
