🔒 Encrypted containers (VeraCrypt)
A safe for confidential files: from the outside an unreadable file, opened with a password a normal drive.
What it does for you
- Tax documents, contracts, ID copies and customer data are readable for nobody – not even us.
- Even if the laptop is stolen, the documents stay secret.
- You work with the files quite normally, as on a USB stick.
Who it is for: Everyone with documents that absolutely nobody may see.
What you need: The free program VeraCrypt (DasDing offers it for download) and a good password. Included in your account.
Copies of passport and ID card, the tax return, medical reports, contracts – these are exactly the files fraudsters look for. In normal storage they are in good hands. In an encrypted container they are additionally unreadable for anyone who doesn't know your password.
How it works
A container is a single, large file. As long as it is closed, it consists only of seemingly random characters. When you enter the password, the program VeraCrypt opens it as a drive – with its own drive letter, like a USB stick. Everything you put in is encrypted automatically when saving and decrypted automatically when opening. VeraCrypt is a proven, free and open program that authorities and journalists use too.
DasDing takes care of the rest: it downloads the container from your storage, opens it, and uploads it again after closing.
Safe
the encryption happens on your computer. Our server never sees the contents – which is why the virus scan can't check them either. Without the password the contents are lost. Store it in the password vault.
Creating a container
- 🏠 Personal area → 🧰 Tools → card “🔒 Encrypted containers (VeraCrypt)”. If VeraCrypt is missing, DasDing offers “Download VeraCrypt”.
- ＋ New container: choose name and size (100 MB to 10 GB). The file takes up its full size in your storage immediately – so don't choose it larger than needed.
- Just leave encryption AES and hash SHA-512 as they are – these are the recommended settings.
- Password (at least 10 characters). Optionally a key file; it is never uploaded.
- Tick “Without this password the contents are lost …” → Create. The container is created and uploaded.
Opening, working, closing
- Open at the container. Windows: choose a drive letter, then VeraCrypt asks for the password in its own window. Linux: enter the password directly in DasDing; the system additionally asks for your admin password.
- The container appears as a drive or folder. Put files in and edit them quite normally.
- At the end click Close in DasDing. Only then are the changes uploaded and the container is available again on your other devices.
While a container is open, it is locked for your other devices – so that two devices don't write into it at the same time and overwrite each other's changes. “Read only” opens it without a lock.
Warning
if you quit DasDing with an open container, it asks. “Close, upload, quit” is the safe choice. Don't switch off the computer before “closed and uploaded” has appeared.
If something goes wrong: previous version
Before every upload the server keeps the previous version for 24 hours. If a sync was interrupted or something is missing, the container shows the button “↩ Previous version”: choose a version, confirm, then open the container again. The current version is not thrown away. Requirement: the container is closed on all devices.
Existing containers
“Import existing container …” takes a .hc or .tc file from your computer into DasDing.
What is the difference from the password vault?
The vault is made for login details (short entries, quick copying). The container is for whole files: PDFs, scans, spreadsheets.
