How to Use Encrypted Buckets
• SynkTanc provides client-side end-to-end data encryption. You can create
encrypted buckets to use this feature. File contents in encrypted buckets are
encrypted on client side. The encryption password is not stored on the server.
So even the server administrator can't access your file contents.
When creating an encrypted bucket:
• If you create an encrypted bucket in the web app, the password is sent to the
server. The server use this password to create the bucket. But it doesn't store
the plain text password.
• If you create an encrypted bucket from a local folder with the desktop client
(see file syncing), the password is not sent to the server.
When you access the encrypted bucket:
• If you use web app, you have to input the password to the server. The server
will cache the password in encrypted format for 1 hour. It won't store the
password on disk.
• If you use desktop client to sync the bucket, the password is not sent to the
server. The client decrypt and encrypt file contents locally. The plain text
password is not stored on the client disk too.
• iOS client supports client side encryption since version 2.1.6. Android client
support it since version 2.1.0.
Note that encrypted bucket only encrypt the contents of the files, but not the
folder and file names.
