LOL, here is "the answer" by ChatGTP. Reads like some of the answers we see here from time-to-time.
That does seem strange. When you open the file in Vim and enter the wrong password, it should not allow you to make any changes to the file or save it. It should only display the encrypted text, but not allow you to make any changes to it. If you are able to make changes to the file and save it even when you have entered the wrong password, then that would indicate that something is not working as expected.
It is possible that there could be some other factor at play here, such as a problem with the Vim configuration or the way that the file was encrypted. Without more information, it is difficult to say for sure what might be causing the issue.
