How to set SMS encryption?

1) Enter the SMS interface, select and press the SMS to be encrypted, and a dialog box will pop up. Select "Encrypted Session" to pop up the password input dialog box (if the password is set in SMS settings first, the new password input dialog box will not pop up, and the encrypted one will be displayed directly). Just enter a new password.

(2) After entering the SMS interface, press the function key, select "Settings" to enter, and click the "Set Password" button. If a password has been set for a message before, after clicking the "Set Password" button, you need to enter the current password (the password of the previously set message) before you can enter a new password. After modification, repeat the first operation.
