[RESOLVED] Name of function

[RoxyBoo]

Hi,

There is in PHP a function that codes words but that does not have an inverse function. So you obtain a string of numbers but only you know the word they represent. I thought the function, or the process was called mdi5, but I can't find it.
Can somebody please tell me the name of this function?
Thanks.

Oh, I posted to javascript, sorry.

It's called md5()

Thanks anyway.
