3. Configure VeraCrypt

Step 1 — Add OpenSC Library Path

1. Go to Settings → Security Tokens → Select Library.
2. Enter the path: C:\Program Files\OpenSC Project\OpenSC\pkcs11\opensc-pkcs11.dll (use the corresponding path for other operating systems).
3. Then go to Tools → Manage Security Token Keyfiles and enter your PIN. You should see the token loaded successfully.

Step 2 — Generate Keyfile

Go to Tools → Keyfile Generator to create a keyfile.

Step 3 — Convert to Base64

# Windows
[Convert]::ToBase64String([IO.File]::ReadAllBytes("keyfile.dat")) | Set-Content -Encoding ASCII "keyfile.dat.base64"

# Linux
base64 keyfile.dat > keyfile.dat.base64

Step 4 — Upload Keyfile to Object Slot

yubico-piv-tool -r MiixKey -a write-object -k --id 0x5fc108 -i keyfile.dat.base64 -f base64
