How to Decrypt and Download Encrypted Files from Cloud Drive?

Scenario Setup​

You need to encrypt files on your TNAS and save them to a cloud drive, and be able to decrypt and download them from the cloud drive back to TNAS for use when needed.

Setup Steps​

Upload Encrypted Files to Cloud Drive for Storage​

You need to create an "Upload local files only" sync task:

  1. Select the sync mode as: Upload local files only;
  2. Check "Encrypt data before sending it to the cloud. Local data remains unencrypted."

Decrypt and Download Required Files​

You need to create a "Download remote files only" sync task:

  1. Select the sync mode as: Download remote files only;
  2. Check "Encrypt data before sending it to the cloud. Local data remains unencrypted."

Click Next, enter the encryption key set during the previous "Upload local files only" sync task creation, and complete the sync task setup following the process; 4. After the sync task is created, you can proceed with decrypting and downloading the encrypted files.

Note

The encryption keys entered in both steps must be consistent to avoid encryption failure due to mismatched inputs;
