Description:
------------
cipher using php code to allow 2 way encryption currently it uses a predefined 
array of Char's it then loops though this and creates every cipher possible by 
shifting the first char to the end in a new array, and as it ciphers one letter 
the cipher moves forward on cipher it's using

No my problem is that i have had to place a check in to make sure the cipher has 
finished if it has and the decrypted cipher is not the same as the original 
string rerun the cipher with the same string,

Now this should not be needed, also this still creates error's

This has been tested in php 5.3.1 and 5.3.3,

The occurrence the same some times refreshing the system give a cipher that's to 
short for the string and this is with the check

whats more annoying is that there is a check in the code to prevent this 
happening as it was happening more and more 

P.S now i got to re-random my cipher base as its useless one made public haha

Test script:
---------------
http://pastebin.com/r934gLpM


inside encryptString you will see 

if($this->decryptString($encoded) === $string){
	return $encoded;
}else{
	return $this->encryptString($string);
}

at the end it should not be possible for me to get a string thats dose not break back.

Expected result:
----------------
The cipher to not occasionally return a string that is to short 

Actual result:
--------------
Using the code above works but keep refreshing it and you will see you will get 
ciphers back that are 2 small a common one for me is "LX" on its own.

this happens more and more with a bigger string in the 

$secure->encryptString
