GoKawiilCryptomator offers open-source client-side encryption for cloud storage files
Cryptomator is an open-source tool that creates encrypted vaults on a user's device, encrypting individual files and their filenames with AES-256 before they sync to services such as Dropbox, Google Drive, OneDrive, pCloud, Nextcloud and ownCloud. It also works offline for local drives, USB storage and network folders, and has apps for Android and iOS. Users can create a recovery key to reset a lost vault password, since Cryptomator itself cannot decrypt files or recover passwords.
GoKawiil's interpretation of the reporting above, not reported fact.
By encrypting files locally before upload, the tool aims to keep data private even if a cloud provider's servers are breached, shifting trust away from storage vendors toward the user. Its open-source code allows independent security audits, which could appeal to privacy-conscious users wary of proprietary encryption claims. However, the lack of any password recovery mechanism beyond a user-stored recovery key means data loss risk shifts entirely onto the user.
- Cryptomator encrypts files and filenames with AES-256 before cloud sync
- It supports Dropbox, Google Drive, OneDrive and several other cloud services, plus offline use
- Lost passwords cannot be recovered by Cryptomator without a pre-saved recovery key
