I could ask my friend and admit that I did not look into it yet and make myself look a little bit lost or try to find the file by myself. I naturally decided to try to find it on my own first and use my friend as a last resort.

The application that helped me find it was the Passware Encryption Analyzer, the free version of it to be precise. This tool scans the computer or selected folders / drives for encrypted or passworded files. It lists everything that is found in a table with information such as name, location, file type and date modified.

The software detects lots of different file types including archives, Microsoft Office documents that have been password protected but also other file types like pdf documents or Bestcrypt files.

The free version has the limitation that it is not able to recover the passwords but that should not be necessary most of the time.

There is no search and domains are sorted alphabetically starting with IP addresses and ending with https urls. If I want to find a password I first have to look for the urls with http which gives me several options, the site could be listed with its IP address, without www or with www. Then I have to do the same for https urls.

Password Finder is a Firefox add-on that adds a search box to the Password Manager of Firefox. Simply start typing numbers or letters and all matching results (sites that is) will be displayed while all others are hidden.

It seems that the add-on is not developed anymore but it works flawlessly with the latest version of Firefox 2.
