5	Choose where you want to store the keyfile (At this step you cannot directly store the keyfile directly to the Token, you first have to save it to your computer and import it to your Token later).
6	Input a password for your keyfile and confirm it. Click on [Next] to continue.
7	Choose the elements that you want to use for password salting and random padding data. We have decided to choose Microsoft CrytoAPI and PKCS#11 Token. Click on [Next].

Unlock the encrypted volume with the keyfile stored in UniToken

1	If you lost the password for your volume, you can now use your UniToken to access the data. Click on [Mount file] (or [Mount Partition] if you encrypted a whole partition).
2	Check [PKCS#11] and when the [Security Token/SmartCard PIN] dialog box appears, fill in your PIN and click on OK.
3	Input the password for the keyfile in the password field and select the right keyfile in the PKCS#11 file. Click on [OK] to confirm and get access to your encrypted volume.
