[DUG] Encryption / Decrption

[Robert martin]

Hi

Yeah my app is actually just encrypt some text and store it in its DB.  
It will Decrypt the information for processing purposes.  The DCPcrypt 
stuff looks great.  However now im left with what to use as a password 
and how to store that in my app.
