Dead-simple file encryption for any OS

Cryptomator is a client-side cloud encryption tool and cross-platform vault manager. It provides a transparent encryption layer that encrypts files and folder structures locally before they are uploaded to a cloud storage provider. The software creates virtual encrypted drives that mount encrypted vaults, allowing users to interact with their data as if it were on a physical disk. It supports the management of multiple independent encrypted containers, each protected by a unique password. The project covers data privacy through directory structure obfuscation and filename encryption to hide
