For someone like me, with mostly website passwords, I don't feel the need of an encrypted, protected password manager. The Mac keychain access is good for the rest.
In case, for the “webPM exported file“: Textedit, the "webPM data file": something like "Peep", works fine. It's good to know that you can at least directly use the data file.
For those who want a free Blowfish encryption password manager, check out: "Password Gorilla" an open source password manager using Blowfish, the ones I found here on VT using Blowfish were all < 0$.
