I use revelation password manager. http://oss.codepoet.no/revelation/wiki/Home

It may not be the most complete manager around but it has everything that you require.

Combine that with dropbox and you can carry your encrypted password file around anywhere you go at any pc you have.

I store everything there.

I just wish there was an android version of it.

Perhaps ill do it one day if i ever manage to find some time !
