Secrets-Editor
The Secrets-Editor is a tool to save text files, images, and other documents in an encrypted form (passphrase encryption with SHA-1 and AES).
The program (text mode) running on Windows
The Secrets-Editor is a simple text editor. When you save a new file for the first time (or when you save an existing file as a new file), you have to specify a password or a passphrase; it will then be used for authentification when you open the file again.
Since version 3.0 you can encrypt arbitrary documents with the Secrets-Editor (see menu add-ons). As one tries to avoid to first decrypt a document, then save it on the hard disk, and then view it with a separate application, Secrets-Editor now supports beside the filetype .txt also the image types .gif, .jpg, and .png, i.e. you may now, for instance, view scanned and encrypted documents directly inside the Secrets-Editor.
Here you can download the program: JAG & the-dom Secrets-Editor 3.2 (Windows Installer). If you don't have installed Oracle's Java Runtime Environment (JRE) so far (or if you have an older version than 1.5), please install first the recent JRE: http://www.oracle.com/technetwork/java/javase/downloads/index.html. Furthermore, the Java Cryptography Extension (JCE) unlimited strength jurisdiction policy files are absolutely required, which are also available at the Java download webpage; two .jar files in your JRE installation (usually located at C:\Program Files\Java\jreXXX\lib\security\) have to be overwritten with the corresponding .jar files from the downloaded zip archive. (For further information or the installation procedure with the JDK please see readme.txt in the downloaded zip archive.)
