If you want the same thing but want to do it in an app instead of manually in the terminal you should check out Notational Velocity (http://notational.net).

Looks interesting.

But only MacOS? No Linux?

Encrypted database? I once tried a password keeper. I think it was called xpassword or something like that. After having a corrupted database twice within days, I pass.

I you want privacy your HDD should be encrypted anyway.

nvpy is a functional but admitedly very ugly linux clone. Both can use Simplenote, which works similarly if you're fine with a webapp.

For the windows crowd there is the also ugly-but-functional ResophNotes.

Encryption is optional. Online syncing (w/ Simplenote) is optional.
