Cryptomator protects files stored with cloud storage providers by encrypting them locally before they are synchronised. It works alongside existing storage services rather than requiring users to move their data to a dedicated encrypted cloud platform.
Users create password-protected vaults that appear as virtual drives when unlocked. Files can be opened and modified using ordinary desktop applications, with encryption and decryption handled transparently. Cryptomator encrypts file contents and filenames while obscuring the directory structure. Unlike applications that package everything into a single encrypted container, it stores files individually, making it particularly suitable for cloud synchronisation.
This is free and open source software.
Key Features
- Uses AES-256 encryption to protect file contents and filenames, with directory structures obscured.
- Creates password-protected vaults accessible through virtual drives.
- Works with Dropbox, Google Drive, OneDrive, Nextcloud and other services that synchronise local folders.
- Encrypts files individually to support efficient cloud synchronisation.
- Uses scrypt for password-based key derivation and authenticated encryption to detect unauthorised modifications.
- Provides recovery keys that can restore access when a vault password is forgotten.
- Supports multiple vaults protected by independent passwords.
