I understand there are plans to add encryption in a future release. I find Yojimbo’s approach completely unusable (which is one reason I’m evaluating Eaglefiler). In Yojimbo you have to enter your password every single time you want to access a password (unless you allow Yojimbo to stash your password in the Keychain, which lowers your security considerably). What I would much prefer would be entering the password upon opening the library and having the entire library available as long as it is open.
Having said that, the ability to simply password-protect a library would proably serve most of my needs. Is this on the list for a release in the near future?
