Key on paper

The Safeberg 'Key on Paper' (or Trusted Paper Key, TPK) is a uniquely printed key. With this key you can easily access the backup of your files whenever you want. Without the Key on Paper, it is impossible to access your files.

The key can be read by means of a photo, scan, or even your mobile phone. This way, you will not have to retype the extremely long key.

The idea for the Trusted Paper Key was developed as an answer to the question: where could a key to all my data be stored best? Not at Safeberg. And not on your computer, due to its vulnerability. Why not on paper...?

 

 

 

How do I use the Trusted Paper Key?

During the installation process of Safeberg, you have the option to choose one of 3 different types of security. When you choose for ‘ultimate security', you can have your Safeberg key printed onto paper (or saved as a PDF on a memory stick).

By printing your key onto paper, it is secured against hackers, a computer crash, or other calamities. Safeberg strongly recommends not saving a copy of your key on your computer.

If you wish to use your key, take a photo or scan it. With this file (a .jpg, .gif or .png file) you can restore your data from the backup.

Suggestions for saving your key:

Without your key, you can not access your files. If you lose your key, Safeberg can not offer you any help.
We advise you to print the key more than once and store it in a safe place.  For example:

  • In your own house
  • With friends or family (besides the key, you also need a Safeberg Password to access your files)
  • In a safe

Technical:

The ‘Key on Paper’ is the Private Key of a 4.096 bit asymmetric RSA key, which is stored in a two-dimensional datamatrix barcode. The key was created based on an Offline Private Key Protocol.
