For those of you who don't know Crypt and MD5 are used in PHP to encrypt things(text, files, etc)

Now the syntax as I understand it is

Code:
crypt:              crypt('$password');
Code:
MD5:              MD5('$password');
Now I belive MD5 converts to a 32 charater string something like

Code:
MD5('Phrase');

/* Converts "Phrase" to .... */

243e61e9410a9f577d2d662c67025ee9
And Crypt uses 12 charaters I belive if using Standard DES-based.

Okay, here is my issue. When I use crypt I get a different out put each time for the same word or phrase.

When Using MD5, I get the exact same string for every word I type in.

WTF is going on? I read on PHP.net something about using a salt, but I'm not sure I get what they are saying. any help please.....
