PrivacyEnvelopeLite 1.2.0 for Mac was available to download from the developer's website when we last checked. We cannot confirm if there is a free download of this app available. The application is included in Security Tools. We recommend checking the downloaded files with any free antivirus. The actual developer of this free software for Mac is Fourth Right Solutions, LLC.
From the developer:
Privacy Envelope Lite will reveal files created with the full version of Privacy Envelope. Its “simple scramble” ability can obscure (but not secure) files. This program will educate the user on what the full version can accomplish. The ability to scramble a file without using an authorization code may be useful to keep the robotic scan of your content by a service provider confused.
