During a discussion over at Ars about password management someone pointed out this page. The page provides an application that hashes a master password and a hostname together to produce a unique password. Using this method one never has to record any other passwords as the application will regenerate it each time you provide the master password and hostname.

Provided one uses a strong enough hash algorithim (at least SHA1) can anyone find vulnerabilities in this method of managing passwords?
