At work I use KeePassX across Mac, Windows, and Linux systems and it does the job fine. At home I really like 1Password for the Mac except that the version I have doesn't work with Safari 5 or Chrome. For secure files on my Mac, I keep a password-protcted & encrypted sparsebundle disk image in Dropbox. You can create one using Disk Utility. It's really handy and always backed up. I can't speak to proving the security of these solutions but work for me otherwise.
