Interface Design and features

Installation is as simple as the built-in wizard guides you through the setup. Cautious users should also verify the PGP signature of the download. The interface is simple when you ask it to be and gives more detail for power users when they need it.



You will be asked if you want to simply install or merely extract the files and run it from there. The advantage being if you want to hide the very existence of Truecrypt, then just extracting it and running it when required is possible. However, to use one of the most useful features you will have to install.

Once setup is complete you are given the standard truecrypt screen, from here you can create new encrypted files, encrypt entire drive letters and mount existing ones. Note that for traveler mode to run, you will need to have administrative access to the computer.

Encrypted Containers



Containers are simply single files that can be given any extension. If you don t want to give away an entire drive for encryption, then you can create a file, which will act like a virtual drive. This container file can be moved, copied and will even appear like any other file. You are given the option to choose the size of this drive; the size of the file container cannot be altered after it is created. If you want a bigger space you will have to create a different container with a larger size and copy over the data to it. The only problem with this is that if the drive on which the container is undergoes defragmentation then sections of the file may remain on the free space left once the process is done. Block device encryption gets around this.

The advantage of this is portability, encrypted internal partitions cannot be moved around as easily as a simple file can. However, this is not always the case, as we will see.

Block device encryption

Truecrypt also supports block device encryption on any kind of partition. This means that apart from encrypting merely one internal drive, you can also encrypt your entire pen drive or external storage device and carry data securely on it. The only drawback here is that when you encrypt your entire drive, the truecrypt program cannot be carried on it in an unencrypted state. You must have other means of getting the program onto the computer you intend to use the data on.

Keyfiles



For either of these modes, apart from choosing a password, you may also choose keyfiles to secure your data. These are files that serve as a supplement to your password and their presence will be required each time you want to open the encrypted files. Any file can be used for this purpose and they provide an additional layer of security, as the correct files have to be specified in addition to correctly typing your password for successful decryption.
