Keepers is a password generating app that uses thousands of iterated hashes (hash of a hash of a hash, etc) based upon secret parameters, namely a passphrase, a PIN, and an individual identification label for each password. Keepers puts the generated password on the clipboard to it is easy for the User to paste into a PASSWORD field. The advantage of using so many hashes is that it is far more difficult for a hacker to start with a known password and work backwards to determine the secret passphrase. They won't even know how many hashes to perform.
