Hey, I haven't coded for about 2 years.

Doing a small project that involves making a translator sort of script which will translate text.

E.g I type in "hello" click a button, and the text that comes out is "fummi" you know like replaces the alphabet with different letters e.g h=f e=u l=m o=i

I've been looking on net for ages and have no idea what to use and so far have got nowhere, hopefully some of you can help!

Can anyone find me or write me some examples?

Thanks in advance, Ash!
