YubiKey Attestation

Attestation

1. Insert YubiKey
   
   

2. Open a Terminal (Linux/Mac) or PowerShell (Windows).

    Windows

   Windows: Run the following to adding the Yubikey Manager cli tools to environment PATH

   Note: you must close and re-open your terminal for these to be picked up

   #User Level
   $newPath = "$env:ProgramFiles\Yubico\Yubikey Manager;" + [Environment]::GetEnvironmentVariable("PATH", [EnvironmentVariableTarget]::User)
   [Environment]::SetEnvironmentVariable("PATH", $newPath, [EnvironmentVariableTarget]::User)

3. Run the following command to attest the certificate in slot 9a
   

   Linux users will need to locate the AppImage and execute ykman command as argument

   ykman piv keys attest 9a <path to save attested certificate>
   ---
   Example:
   (Windows) ykman piv keys attest 9a %USERPROFILE%\%USERNAME%-attest.pem
   (Linux) yubikey-manager-qt-***-linux.AppImage ykman piv keys attest 9a $HOME/$USER-attest.pem
   (Mac) /Applications/YubiKey\ Manager.app/Contents/MacOS/ykman piv keys attest 9a $HOME/$USER-attest.pem

4. Run the following to pull the intermediate certificate from slot f9

   Linux users will need to locate the AppImage and execute ykman command as argument

   ykman piv certificates export f9 <path to save attested certificate>
   ---
   Example:
   (Windows) ykman piv certificates export f9 %USERPROFILE%\yubico-intermediate-ca.pem
   (Linux) yubikey-manager-qt-***-linux.AppImage ykman piv certificates export f9 $HOME/yubico-intermediate-ca.pem
   (Mac) /Applications/YubiKey\ Manager.app/Contents/MacOS/ykman piv certificates export f9 $HOME/yubico-intermediate-ca.pem

5. Provide certificates to Systems or IA team member.
   This step will require a face-to-face meeting or camera-enabled Zoom meeting.
   This step is mainly required for access to Linux servers.

   This is still being tested, but we are using this for now.

   Paste all the contents of the file, including the "BEGIN/END" statements

   If submitting multiple certs, each certificate must be merged before new can be added (I believe this is true, needs verification)
