Personalization

Although you can put custom laser engraving on Cryptoucan’s body, having editable user identification inside the device may be very useful. Learn how to change the name and gender of its owner and, on top of that, see how to change settings that will ask you to enter user PIN every time you’ll try to sign an e-mail.

Generating keys

Before you’ll be able to sign your messages and decrypt encrypted e-mails sent to you, you have to get your own set of cryptographic keys. In this article you’ll find step-by-step guide for this process.
■ ■ ■

Changing PIN codes

The key to privacy and security is having your own passwords that are known only to you. Make sure your information and secret material is always secure by setting up your own PIN codes. This article will show you how it’s done.
■ ■ ■

Key management

To be able to send encrypted e-mails, you’re going to need other users’ public keys. This article will show you how to import keys, how to certify them and how to export your public key for others to use.

Signing, Encrypting, Decrypting

To make your e-mails truly private, you need to encrypt them first. You can also sign your e-mails so the person on the other side of the conversation knows for sure it was you who sent them. Learn this in this article as well as how to decrypt e-mails sent to you.

Linux + Thunderbird

Basic operations

There are two basic operations that you will probably be doing with your Cryptoucan™ all the time – signing documents and decrypting encrypted messages someone sent you. Cryptoucan™ will do both operations for you, it only requires from you to enter your user PIN 1. This article will guide you through the process of entering appropriate PIN – how to submit the PIN, what should you do if you missclick and what happens if you enter incorrect PIN.
■ ■ ■

Privileged operations

If you’ll ever be generating your own set of cryptographic keys or setting up new user PIN code, which you probably will as a part of the device initialization, you’re going to need to use administrative PIN 3. This article contains all the information about administrative PIN 3 – when to enter the PIN, how to submit it and what happens if you enter incorrect PIN too many times.
