So if I did a salted sha256 followed by 8 rounds of bcrypt each with their own unique salt (probably a bad idea and I know it) you would know that I started with sha256? Wouldn't the final round of hashing obscure all previous rounds? And how would you strip away a salt without having the original, unhashed information? The whole point of a salt is to be factored in prior to the hashing process. Also, you don't decrypt hashes.
