Hash Function

Hello folks.
I come a cross Lee Mac's MD5 Hash function
http://www.lee-mac.com/md5.html
that converts any string to hash encrypted string.
Thank you Lee for that great function.
Is it possible to convert the return string back?
Many thanks in advance.

Thank you for your kind answer and confirmation.
Sorry, just another question come up to my mind.
Could the return of Hash function be by any chance the same as any other random string? Is it unique return string all the time?
Thanks again.

You use a hash to preform a checksum (to verify what you have is what you expected). So, no random string will suffice.
