How To Use Cryptomator With Securecloud.nz For Client-Side End-To-End Encryption

End-to-end encryption (E2EE) is a security method that ensures your data is encrypted on your device before it is uploaded, and can only be decrypted by you or those you explicitly share it with. This means that even the cloud storage provider cannot access the contents of your files. In the context of SecureCloud.nz, E2EE provides peace of mind by keeping sensitive business documents, creative projects, and personal files fully private while still allowing seamless cloud access and collaboration. It combines the convenience of cloud storage with the strongest protection against unauthorized access.

Cryptomator is an open-source tool that makes this easy, and it works seamlessly with SecureCloud.nz via WebDAV.

This guide will walk you through setting up and using Cryptomator with SecureCloud.nz, step by step.

What You’ll Need

  1. A SecureCloud.nz account
  2. Cryptomator installed on your device (Windows, macOS, Linux, iOS, or Android)
  3. WebDAV access enabled on SecureCloud.nz (WebDAV is a standard protocol that allows encrypted access to your files over the cloud)

Step 1: Enable WebDAV on SecureCloud.nz

  1. Log in to your SecureCloud.nz account.
  2. Go to Settings → WebDAV (or similar in your dashboard).
  3. Take note of the WebDAV URL, your username, and password. You’ll need these for Cryptomator.
  4. Make sure WebDAV access is active.

Step 2: Install Cryptomator

  1. Download Cryptomator from cryptomator.org for your device.
  2. Follow the installation instructions for your operating system.
  3. Launch Cryptomator.

Step 3: Create a New Vault

  1. In Cryptomator, click Create New Vault.
  2. Choose a location to store your vault locally (this is where your encrypted files will temporarily reside before syncing).
  3. Name your vault something descriptive (e.g., “SecureCloud.nz Vault”).
  4. Set a strong password for your vault. Remember: Cryptomator does not store your password. Losing it means losing access to your files.
  5. Click Create Vault.

Step 4: Mount the Vault

  1. Once the vault is created, select it in Cryptomator and click Unlock.
  2. Cryptomator will mount the vault as a virtual drive (e.g., on Windows it appears as a new drive letter; on macOS, it appears in Finder).
  3. You can now drag and drop files into this virtual drive—they are automatically encrypted before leaving your computer.

Step 5: Connect to SecureCloud.nz via WebDAV

  1. Open your favorite WebDAV client (or use your operating system’s built-in support for WebDAV).
  2. Enter your SecureCloud.nz WebDAV URL, username, and password.
  3. Map the WebDAV folder as a network drive (Windows) or connect via Finder (macOS) or file manager (Linux).

Step 6: Sync Your Vault to SecureCloud.nz

  1. Once your vault is mounted in Cryptomator, copy or move your files from the vault to the SecureCloud.nz WebDAV folder.
  2. The files stored in the cloud are now fully encrypted. Even SecureCloud.nz cannot access their contents because the encryption is handled entirely on your device.
  3. Future updates: any file changes you make in the mounted Cryptomator vault can be synchronized to SecureCloud.nz via WebDAV manually or with a sync tool.

Step 7: Access Your Encrypted Files Later

  1. To access your files, download the encrypted vault from SecureCloud.nz to your device.
  2. Open Cryptomator and unlock the vault with your password.
  3. The virtual drive will appear again, and you can use your files as usual.

Tips for Best Security

  • Always use a strong, unique password for your Cryptomator vault.
  • Consider backing up your vault password in a secure password manager.
  • Keep your local Cryptomator installation updated to the latest version.
  • For mobile access, Cryptomator apps on iOS and Android allow direct access to SecureCloud.nz via WebDAV, so you can unlock your files on the go.

Why This Setup Works

  • Client-side encryption: Only you can decrypt your files. Even if someone gains access to your SecureCloud.nz account, your data remains safe.
  • Reliable New Zealand storage: Your files are stored on local servers in New Zealand, providing fast access and legal data residency.
  • Backup reliability: Using WebDAV with SecureCloud.nz ensures your encrypted vault has an additional copy that won’t fail like an external hard drive.

By combining Cryptomator with SecureCloud.nz, you get the best of both worlds: the security of client-side encryption and the reliability of a cloud backup stored safely in New Zealand.
