Welcome to Part 3 in my series on protecting your computer from prying eyes (Part 1, Part 2). In today’s segment, we will be going over drive encryption using the TrueCrypt program on Windows OS. Drive encryption is a technique that masks your data with a cryptographic function. The encryption header stores the password that you have entered for the archive, which allows the data to be reversed and read from. Encrypted data is safe from anyone who wants to read it, other than people with the password. As long as the password is strong enough, the data can never be read, thus, it is protected.
Encryption can exist on a whole hard drive, or just a partition. TrueCrypt even allows you to use it to create encrypted containers that can store files in them.
In today’s Null Byte, we are going to be using Windows and TrueCrypt to encrypt our data. This is useful for a number of reasons; keeping data private, negating negative side-effects of having data stolen, viruses/malware can’t read your files, and more. This protects all of your data, regardless of circumstances.
Let’s get started.
- Minimal computer literacy
- Admin privileges
- Windows OS
- If you edit partition sizes, you may lose data (not required).
Step 1 Download & Install TrueCrypt
First we need to install the TrueCrypt software.
- Download TrueCrypt here.
- Navigate to the Downloads directory.
- Double-click the installer.
- Click Next > Next > Install.
Step 2 Encrypt a Drive or Partition
