Cryptoucan™ usage: Personalization

Written by Lída Hrnčířová on April 25, 2019.

In this blog post we will show you which personal information stored on Cryptoucan™ you can modify and what software to use. This is accompanied by instructional video for Windows that will guide you through the whole personalization process.

Although Cryptoucan™ has laser engraved customizable markings[1] on the backside, it can be handy to have editable user identification, too. We understand that our device can be bought by companies that do not want to permanently assign the tokens by engraving user’s name on it. That’s why you can have holder’s name inside. This gives you the opportunity to re-use tokens.

If you want to see the step-by-step video guide, feel free to watch this video.

This personalization can be done using Thunderbird e-mail client[3] with Enigmail add-on[4]

If you want more information on the software mentioned or you don’t have some of the software installed and you want to get help with the installation process, visit this blog post.

As you can see, these are the fields you can edit:

  • Firstname, Name – this is the most important field if you want to make sure that you can easily find out the holder’s name,
  • Language – setting up the language doesn’t have any impact on functioning of the device but if you want to set the language anyway, use the standard ISO 639-1[5] which assigns two letter abbreviation to each language,
  • Gender
  • URL of public key – in case you want to use your Cryptoucan™ on multiple computers, having a valid public key URL here will help GnuPG recognize your token,
  • Login data – typically your login username if you plan to use Cryptoucan™ for authentication,
  • Force signature PIN – by selecting “yes” in this field, Cryptoucan™ will ask you to enter user PIN every time you try to create a digital signature.

Make sure to pay attention to the “Firstname, name” and “Force signature PIN” fields. Other fields are not as important as these two since “Firstname field” will help you with identifying the holder of the device and “Force signature PIN” is an important security feature. We strongly recommend you to choose option “yes” in the latter one for security reasons.
