Cryptomator: Turn Your Cloud Drive Into a Secure Private Vault

Solves in one sentence: Not comfortable storing your files on cloud drives? Cryptomator encrypts them automatically before upload, so even if your cloud drive gets hacked, nobody can see your files.

Using OneDrive, Dropbox, Google Drive, or Baidu Cloud to store files is certainly convenient. But what about security? These files are stored in plain text on the cloud provider’s servers. The providers themselves can see them, and so can hackers if they breach the servers.

Cryptomator’s solution is brilliant: encrypt files on your computer first, then sync to the cloud.

What Is Cryptomator?

Cryptomator is a transparent encryption tool for cloud files. When you work with files locally, you won’t even notice the encryption is there (automatic encryption/decryption), but the files synced to the cloud are all encrypted gibberish.

The problem it solves: Enjoy the convenience of cloud sync while ensuring only you can read your file contents.

User Experience

Here’s how the workflow works:

1. Create an encrypted vault on your computer
2. Place the vault inside your cloud sync directory
3. Unlock the vault and use it like a normal folder
4. Drop files inside, and they’re automatically encrypted
5. The cloud syncs the encrypted version
6. On another device, install Cryptomator, unlock the vault, and files are automatically decrypted

Comparison with VeraCrypt

Feature	Cryptomator	VeraCrypt
Use Case	Cloud file encryption	Local disk encryption
Method	Per-file encryption	Full container/disk
Cloud-Friendly	✅ Auto-syncs encrypted files	❌ Not suitable
Mobile Support	iOS/Android	❌
Free & Open Source	✅	✅

Cryptomator is best paired with cloud drives, while VeraCrypt is better for encrypting entire hard drives or USB drives.
