By definition of symmetric encryption, you must use the same key to  
decrypt that was used to encrypt. I'm not sure what you're really  

When you say "public key is used to generate symmetric key" you lost  
me. Symmetric keys are typically just random numbers pulled from /dev/ 
random or similar.
