Cryptomator
Client-side encryption for your cloud files — a German open-source alternative to Boxcryptor.
About
Cryptomator is a German open-source encryption tool that adds client-side, zero-knowledge encryption to any cloud storage service — Dropbox, Google Drive, iCloud, OneDrive, or S3-compatible storage. It creates an encrypted vault that appears as a normal folder; files are encrypted before they leave your device and decrypted only on your device. Cryptomator is developed by Skymatic GmbH in Bonn, Germany, is licensed under LGPL, and is audited by Cure53. It enables EU teams and individuals to use any cloud storage service without trusting the provider with the content of their files — a practical solution for GDPR compliance when using US-based storage that is otherwise convenient or mandated by organisational policy.
