Introduction

The guides in this book require one device of any in the following categories:

• YubiKey 5 Series

• YubiKey 5 FIPs Series

PIV is a technology / interface on your Yubikey, which stands for Personal Identity Verification.

This interface allows you to create certificates which are stored on your Yubikey in the PIV interface and interact with non-web interfaces / applications.

Importing certificates in your PIV allow you to do some cool things such as:

• Unlock a Bitlocker or Veracrypt encrypted drive.

• Sign into a server you own with SSH (even passwordless if you want).

• Sign documents with programs like Adobe Acrobat.

• Sign code with programs such as Microsoft's Signtool or Windows Powershell's Set-AuthenticodeSignature command.

• Sign Windows .cat catalog files

Using a module is optional. If none of the above examples interest you, then you can leave PIV alone on your Yubikey.
