  Subject: [PHP] crypt and decrypt a string
 
 
  Does anybody have an easy way to crypt and decrypt a string?  I see the
  Mcrypt Encryption module but thats a little more gung-ho than I'm
  looking for.  I'm not trying to encrypt sensitive data rather I'm more
  trying obfuscate it a variable for a hidden tag.
 
  Thought I remember seeing something using XOR?  Any ideas?
 
  Thanks
  Joel

Exactly what I was looking for.

Thanks

From the PHP doumentation on crypt:

There is no decrypt function, since crypt() uses a one-way algorithm. so
that wouldn't have worked.
