Self-Decrypting Packages

east-tec InvisibleSecrets offers a new function: creation of Self-Decrypting Package (SFD). Using this function you can create a executable package with encrypted content. Before encryption the files are compressed. After the package is created you can send it by email. All the receiver needs to decryption the package is the correct password (no need of special programs), since the package is a program itself.

To create a SFD Package you have make the following steps:

1. Select the action: Self-Decrypting Packages

3. Add a message to your package

You can add a message to the SFD Package; this message will be shown after the receiver of the package will decrypt the package. This message is useful because you can transmit instructions, read-me files, or other comments to the receiver of the package.

Message added to the Self-Decrypting Package

You have several possibilities to format the message: font, size, color etc.
