Many of us are guilty of the same crime against computer security -- using one password across many websites. If someone manages to lift your password from one low-security website, they have a good chance of using that same password at many other sites. PwdHash uses a user-generated password, the URL of the website you're visiting, and a pseudo random function to transparently transform the user's password into a domain-specific hash of the password. If someone steals a password file from a website, they're only getting a hash for that domain -- not the user's actual password. The fact that the hash is generated for a particular domain also acts as an effective defense against phishing scams.
The same function is used across platforms, so regardless of what type of operating system you're using with PwdHash, the same user password will generate the same hash. You can use the Firefox browser extension on your Mac or PC, the PwdHash.com website on any computer, or KeyGrinder on iPhone, and your generated hash will open the proverbial gates. KeyGrinder isn't the most visually attractive app you'll ever see, but it doesn't need to be pretty. To generate your hash, you enter the address of the site you wish to visit and your user-generated password. Press the create button, and the hash code appears, ready for you to enter as a new password for a website. With KeyGrinder, you can enter a number of web addresses and create each of the hashes, then call them up later by using a standard picker to select a site and generate the hash with a single tap.
You can choose to have the app open a website as soon as the hash has been generated. The hash is automatically copied to the iPhone clipboard for pasting into the password field for your favorite site.
