SecretPad

SecretPad provides an interface similar to that of Notepad and it provides functionality similar to that of Notepad. This means that you can open a SecretPad file and type in or copy/paste any text you want. Unlike Notepad, SecretPad provides support for URLs and it password protects files. The text you enter in a SecretPad file is thus protected from snoopers.

No installation is required to get started with SecretPad. All you have to do is download a very small executable (less than 100KB in size, as a matter of fact) and run it. Of course, this means that SecretPad is portable. Put it on a USB stick for example and you can take it with you.

When you launch SecretPad, you will be prompted for a password. Said password will protect the file you create. After that you will be presented with a Notepad-like interface: a large panel for entering text, a File Menu at the top. When you’re done entering the text you want, you can save your work as an encrypted and password-protected .CDT file. Anyone who wants to access said file will have to provide the correct password. And since you're the only one who knows it, only you can decrypt the file and access the text inside.

Speaking about text, it must be mentioned that SecretPad provides Unicode support, detects URLs, allows you to play with the text formatting, allows you to find and replace text, and lets you print out text.

SecretPad is freeware. You can use the application for free for as long as you want.

Type in anything you want just like you would with Notepad. But since you’re using SecretPad and not Notepad, you can encrypt and password protect anything you type in.
