From the developer:
OperaPassView is a small password recovery tool that decrypts the content of the Opera Web browser password file (wand.dat) and displays the list of all Web site passwords stored in this file. You can easily select one or more passwords in the OperaPassView window, and then copy the passwords list to the clipboard and save it into text/html/csv/xml file.
You may want to check out more software, such as Keylogger Hunter, #1 Anonymous Proxy List Verifier or WildBlue Security Center, which might be similar to OperaPassView.
