Your files live in the cloud. Only you and your team can read them.

Krywerk encrypts folders in OneDrive, Nextcloud or on your NAS and shows them to you as an ordinary drive.

The same folder: on the left as you and your apps see it – on the right as it is stored with the cloud provider.

What makes Krywerk different

Work as usual

The encrypted folder shows up as a drive. Word, Excel, your file manager and every other program use it like any folder – encryption happens in the background.

Team folders without a shared password

Access comes from your organization account, for example Microsoft 365. Keys are managed by a server you run yourself – it never sees a single file.

Open and independent

Krywerk is free software and uses the open Cryptomator format. No account with us, no telemetry, no license limits. Boxcryptor data can still be opened and converted.
