Ask qq to send information encryption method.

QQ, like other software, needs certain security measures to prevent your QQ information, such as your conversations with netizens, from being snooped. In addition to the computer's own security measures, such as power-on password, screen saver password, etc., you can also set QQ security in QQ.

When QQ sends a message, the message received by the other party is stored in the file in the local directory, especially the MSG file. These files are encrypted and cannot be deciphered by others, although they can be seen and copied in the corresponding directories, and the encryption measures taken are very safe.

In addition, you can protect QQ and set a local password: enter the local password, with at most 16 digits. The password prompt question is optional. If you choose, be sure to remember two passwords, or forget that no one can help you. After setting the local message password, you must enter the password correctly when you start QQ. If you can't remember, you can click "Password Prompt" and fill in the correct answer. As long as the local message password is set, people who don't know the password can't see the information in your QQ anyway, even if they steal the file.
