Error messages are nightmares to a programmer. Default error messages are annoying and looking ugly. And kind of security threat as well. You probably wish to show a custom message when an error occurred. And tried and failed? I had written this small code snippet for one of my projects and now wondering if this…

So, how to encrypt a string? Just call this function and pass your string. Additionally set your second parameter to ‘e’ (optional). To encrypt Hello World!, write-
