Cypherdog Key Manager

Step 1: Choose your operating system and download Cypherdog Key Manager for Cypherdog E-mail Encryption!

The application works 14 days with all features, after that you can decrypt received e-mails or you need license code to still have all features. The application is downloaded from the Cypherdog website, not from the Microsoft Store / App Store platforms, therefore, in some operating system configurations, a warning about the origin of the application may appear.

Step 2: Install plugin to your browser or standalone application.

Tip during installation:

Windows Defender blocks some features of Cypherdog by default because it uses network sockets, and this type of network traffic is blocked by default in Windows. When the warning generated by the Windows firewall is displayed, please allow access by selecting the appropriate network type (if you do not know which type of network you should choose both items).

Apple - some versions of operating systems require changing the settings to those that allow the installation of applications from outside the Apple Store
