I’m learning to use a really cool text editor called vim. It is a fast and powerful text editor, but it is not as easy to use as programs like Notepad or TextEdit.
One thing I discovered is that is is really easy to encrypt your text files with vim. You can even use the Blowfish encryption method, which if I understand correctly, is a really good encryption method. TechRepublic has a helpful article about using vim to encrypt text files.
