What’s Cryptomator.exe? Is it safe or a virus?

Cryptomator.exe by Skymatic GmbH is the Windows executable for Cryptomator, software designed to provide data encryption for cloud storage. It creates secure, virtual vaults encrypted with AES-256 to protect files and folders, ensuring that even if cloud storage is compromised, the data remains inaccessible without proper authentication. Cryptomator operates with transparent encryption, allowing users to view, edit, or manage files within the vault as if they were local files. It maintains a user-friendly interface and seamlessly integrates with popular cloud providers, enhancing data privacy without compromising convenience. The software emphasizes security, open-source integrity, and ease of use across platforms.

What does it mean if someone is the publisher of a PC .exe (executable or process)?

The publisher of an executable is the entity responsible for its distribution and authenticity. Most processes/executables on your PC should be signed. The signature on the executable should have been verified through a third party whose job it is to make sure the entity is who it says it is. Find an unsigned executable? You should consider scanning any completely unsigned .exe on your PC.
