iPhone/OS X LION: How to retrieve the decoded data from the CC_SHA256 encrypted data?

Question

I am encoding NSString input using the following code (CC_SHA256). Could someone help me retrieving in decoded format using the same logic?

    -(NSString*) enco         


        

Answer 1

You can't SHA is a hashing algoritm, not ment to be decoded.

Like Jonathan Grynspan said, if you could decode sha (any version) would defeat the purpose of such an algorithm.
