Install the PKI Package

This section explains how to install the PKI package that can be found inside the UniToken SDK. The End User package can be found inside the folder "Redist/Enduser/".

1	Right-click on the PKI package installation file and choose [Run as administrator]. Execute the file with an account that has administrator rights on this computer.
2	Click on [Next] in the InstallShield Wizard welcome screen.
3	Input your User Name and Company Name and click on [Next].
4	Select [Complete] and click on [Next].
5	Click on [Install] to begin the installation of the PKI package.
6	Verify that the InstallShield Wizard completed successfully and click on [Finish].

Configure PKCS Support in FreeOTFE

1	In the main menu, go to [Settings], [Security Tokens].
2	In the [Options] window, under the [PKCS#11] tab, check [Enable PKCS#11 support] and locate and select the library file. By default, the PKI package will install this file in the Windows\System32\ directory. Choose where to save the settings in the field [Save above settings to] and click on [OK] to apply the settings.

Create an Encrypted Volume with FreeOTFE

1	To create a new encrypted volume under FreeOTFE, click on [New].
2	On the FreeOTFE Volume Creation Wizard welcome page, click on [Next] to begin the volume creation procedure.
3	You can choose to store the encrypted volume as a file or to encrypt a whole partition/disk. Choose the option that best fits your purposes. In this example, we have chosen to store the encrypted volume as a file. Click on [Next] to continue.
4	Choose where you want to store the volume and click on [Next] to continue.
5	Choose the size of your encrypted volume and click on [Next] to continue.
6	Select the encryption algorithm you wish to use to best fit your needs, otherwise continue with the default option. Click on [Next] to continue.
7	Choose the elements used to secure your volume. The more number of options you select, the more you can secure your volume. We have chosen to use the "Microsoft CryptoAPI" and "PKCS#11 token" options. Click on [Next] to continue.
8	Check that you have selected the right UniToken device and click on [Next] to continue.
9	Input a password for your encrypted volume. This password doesn’t have to be the same password used on your UniToken. Click on [Next] to continue.
10	Check that the details for the new volume are correct and click on [Finish] to create the volume.

Creating and Storing a Keyfile for the Encrypted Volume within UniToken

1	In the main menu of FreeOTFE, click on [Tools], [Create keyfile…].
2	Choose the type of your encrypted volume, either a file or a partition. In this step, we have chosen "File". Click on [Next] to continue.
3	Indicate where your encrypted volume is located and click on [Next].
4	Input the password of your volume and change the supplementary options if desired, then click on [Next].
5	Choose the directory where you wish to store the keyfile (At this step you cannot directly store the keyfile to the token. You must first save it to your computer and then import it onto your token later).
6	Input a password for your keyfile and change the supplementary options if desired. 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].
8	Check that the correct UniToken is selected and click on [Finish].
9	In the main menu, choose [Tools], [PKCS#11 token management].
10	Input the PIN for the UniToken and click on [OK].
11	In the [Keyfiles] tab in the "Security Token/Smartcard Management" window, click on [Import] and select the keyfile that you just created.
12	When the dialog box [Keyfile imported successfully as: (Name of the keyfile)] appears, importing of the keyfile has finished. For improved security, you can choose to securely delete the keyfile stored on your computer and keep only the one inside the UniToken.

Unlock the Encrypted Volume with the Keyfile stored in UniToken

1	You can now use your UniToken to access the encrypted data. Click on [Mount file] (or [Mount Partition] if you encrypted a whole partition) in FreeOTFE.
2	Select [PKCS#11] in the "FreeOTFE Key Entry" window, and under the "Security Token/SmartCard PIN" dialog box, input your PIN and click [OK].
3	Input the password for the keyfile in the "Password" field and select the correct keyfile in the PKCS#11 file. Click [OK] to confirm and access your encrypted volume.
