How to Create an Encrypted File on your USB key with a Hidden Volume

This guide will show you how to create an encrypted file that can be stored on a USB key. This encrypted file can be mounted as a virtual harddisk and contains two partitions, one to be used to store innocent files that you are happy to share with a password you can give up and a hidden partition that can be accessed by the use of a secondary password.

Creating the Encrypted File

• Open Truecrypt
• Click Create Volume
• Create and Encryped File Container

• Select Hidden Truecrypt volume

• Normal Mode

• Create a File on your USB key (d:\futurama.avi)

• Keep the Encryption as default

• Specify the outer volume size (this is the public volume, There is a 4gb max filesize on FAT32)

• Create a password i.e. (PUBLIC123)

• Click Format to create the encrypted file

• Open the outer volume and copy over some dummy files

• Create a hidden volume, Keep the encryption standard

• Choose the size of your hidden partition (less the Public Partition)

• Create password for hidden volume (HIDDEN123)

• Format your hidden partition

Warning – Adding files to your outer volume can overwrite files in your hidden volume (This is by design so no one knows there are hidden files)

Mounting the Encrypted File

• Open Truecrypt, Click select file and find your file

• Enter the password for your hidden partition, or if you don’t want your private files to been seen input your public password
