cryptomator

Boxcryptor has been acquired by Dropbox and will terminate free accounts as of January 31, 2023. Till then, all users have to look for an alternative. It is not clear how customers with existing contracts are served in the future and no new accounts are accepted. So why not use Mountain Duck with support for the Cryptomator vault format independent from a single provider?

Smart Synchronization

Mountain Duck allows you to mount multiple cloud storages and servers as network drives on macOS and Windows using Smart Synchronization for offline access. Use the built-in, fully interoperable support for Cryptomator vaults to encrypt your sensitive data in password-protected vaults with end-to-end and zero-knowledge encryption. You do not need to have the Cryptomator apps installed but can access the same vault using Cryptomator for iOS for example.

Interoperable

Cryptomator is free and open-source software with no security by obscurity, no hidden backdoors from third parties, no need to trust anyone except yourself. No online services, no subscriptions, no accounts.
