I just tested AES Crypt and it’s dirt simple. But it lacks a password retention option (ease of use) and won’t wipe the original files for you. You also have no option to show the password, which can be useful for longer ones typed twice. I’d call it a bit too crude, but interesting.
I could see using it along with AxCrypt2Go but I’d have to convince several relatives to install it first! I installed AxCrypt 1.x onto their PCs years ago and they’ve never once sent me an encrypted file (testament to perennial novices or apathetic users).
