MyText is a small, portable alternative for Notepad that supports text encryption.
It features the encryption of text files by the ETXT format and includes a password encryptor.
If you've become accustomed to using Notepad, you should have no problem getting comfortable with MyText. It has a clean, simple interface and drop-down menus you will be familiar with; File, Edit, View, Format, Tool, and help.
Below that, you'll find icons you normally see in WordPad for commonly used commands; New, Open, Save, Copy, Paste, Cut, Print, and Help. Screenshot #2 below shows NotePad and MyText side-by-side.
Another neat feature most might not notice is that RoboForm recognizes it so you can safely store your passwords.
If you're using NotePad and want encryption, you're looking at a perfect, free solution.
