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…
Update: I have released Ncrypt, a library (OOP based) that facilitates the same. See here This function will provide you a two-way system to encrypt a string or decrypt an encrypted string.
