Encryptopad в Android Market

Encryptopad (v. 2.0) Разработано Rene Grothmann

A reader and editor for encrypted text files, compatible with the file format of Encrypted Notepad Extended, a desktop program for Java. The encryption is secure and safe.  The source is open. A desktop version is available from the program homepage.

This is a very convenient way to store secret information, like passwords or access codes. No external encryption service is needed.

Files can be stored in Dropbox folders, and the editor will start from there, or from any other file manager.
