  1. Has the DriveCrypt encryption ever been broken/hacked?

No! In the past, we have also launched several contests offering up to 100,000 US$ for the first person able to open a DriveCrypt encrypted disk
Nobody succeeded!

10.  We are from the "Police" "Tax authority" "Security Company". and are investigating on someone whose computer is protected with your DriveCrypt software. Since we were not able to break into the protected computer ourselves, could you please assist us getting access to the encrypted data? If requested, we can provide you with a court order.

Sorry, but our software has been designed to be the most secure in the industry, and as such not even our programmers are able to break into a DriveCrypt encrypted computer.
The only way to get access to the protected data is by entering the correct password known only by the legitimate user.

11.  Is there a back door in your software?

No. There is no back door in our software, and there is no point in making one as we might risk losing the good reputation of our products. Besides this, today there is no law in Germany that can force us to make one in our software.

12.  Have you ever been asked by any government to add a "back door" to your software?

We have never been asked by any government to add a back door into our software, and we have no interest in making one. In any case, no country in the world, other than Germany (where SecurStar is incorporated), can force us to put a back door in our software. Please note that we incorporated SecurStar in Germany, because Germany is one of the few governments in the world that actively promotes strong cryptography while other countries are more restrictive on this subject matter. If laws in Germany should change in the future, we are prepared to move the company accordingly.

13.  Is the source code of your software available?

With our former products Scramdisk and E4M we had a long tradition of open source software. With these products, millions of people all over the world could verify the software security and review how the encryption functions. Unfortunately our competitors had nothing better to do but to steal our source code to add routines and functionalities to their (closed source) products. Some also just cloned our software and only changed the user interface.
Since we want to avoid spending a tremendous amount of money and time in research and development to see competitors stealing our work, we decided to release the source code only to selected customers after they placed a substantial order and signed a non-disclosure agreement.
We are open to other ways of releasing the source code to the public, but need to find a solution that can also protect our interests. One idea we had was to release a basic version of our software together with its source code. This way, the most paranoid can use that software to encrypt/ decrypt the data. Please let us know if this would be acceptable for you, or if you have any other interesting idea that covers the above problematic. We would be more than happy to listen to you. Please write to contact@securstar.de

  1. I have forgotten my password. Can you help retrieve it?

For security reasons there are no "back doors" in DCPP, this means that if you loose your password you loose your data. Password recovery options are useful but defeat the entire purpose of full disk encryption, If you forget your password there should be absolutely no way for you (or anybody else for that matter) to retrieve it again. Take your passwords seriously and understand that if you forget your password there is ABSOLUTELY NO METHOD of retrieving it again, not even by the creators of DCPP.

Although this seems a bit harsh it ultimately enhances the security of your data (which is why you're using this product).

Choosing a secure yet easy to remember password is not a trivial task, if you need help doing this please see the Creating a Secure Password section of the software’s helpfile.

SecurStar GmbH (the creators of DCPP) and it's associates cannot be held responsible for you forgetting your password.

You can then view which version you are allowed to register and the date of when the service expires/expired.

Can I use SurfSolo VPN for P2P File-Sharing and Tor?

While most other VPN providers don’t like this, at SurfSolo VPN we don’t care.
You can use TOR, eMule, or any other P2P system as you like.


In my country, many homepages are blocked or censored. Would I be able to access those sites using SurfSolo-VPN ?

When you use SurfSolo-VPN, your internet or service provider is completely bypassed. The internet thinks you are in another country and as such censorship or other restrictions will no longer apply.

May I use SurfSolo VPN to do illegal things ?

Definitely NOT!- If you plan to do illegal things including email spamming, hacking, sharing child pornographic material etc… don’t  become our customer !

Do you store any of my online activity data?

We don’t store any of your online activity data (we keep no logs).


We are from the Police and need information’s about one of your customers …

The SurfSolo-VPN team is a strong believer in online privacy; this is one of the main reasons why we have created the SurfSolo product. According to German law we are not required to keep logs of any of our customer’s online activity and as such we are not keeping any. This means we have no information at all to share regardless of the particular situation.

Should I keep the firewall enabled or disabled in SurfSolo VPN?

By the default the proactive firewall is enabled in the software for security reasons. This will ensure that no malware on your computer (virus or security vulnerable software) may leak out your real IP address. The firewall will however also block access to your local network, remote drives or server. If you need to access to your local network just turn the firewall off from the “settings” panel of the SurfSolo-VPN software.

Can I select which software and browser go through the VPN?


With SurfSolo-VPN all your applications will automatically go through the VPN.
If you wish to configure only specific software to surf securely, then you can download our old SurfSolo 3 client here:

You will need to enter the following details into SurfSolo 3:

Server: firecrypt.com
Username: Same one you received with your SurfSolo VPN subscription
Password: Same one you received with your SurfSolo VPN subscription
Port: 4426

For the program “X” define a new forwarding in SurfSolo with the port number “xxxx” (a number between 1024 and 65535).
When adding the port forwarding you need to choose a local port that it is not used by another program. Then go to your X program proxy server settings and set the proxy host to and the proxy port to the port that you forwarded (“xxxx”).
