Do you know how to use string encryption

[androiddisk]

After compiling the original string, the binary can be directly opened to view the used string.

    let my_string = "Hello, world!";

I will now use ASCII for the string and then convert it back to the string

    let my_string = String::from_utf8_lossy(&[72, 101, 108, 108, 111, 44, 32, 119, 111, 114, 108, 100, 33]);

Please evaluate the safety
