The Forensic Toolkit, or FTK, is a computer forensic investigation software package created by AccessData. It examines a hard drive by searching for different information. It can, for instance, find deleted emails and can also scan the disk for content strings. These can then be used as a secret key word reference to break any encryption. The toolbox incorporates an independent disk imaging program called the FTK Imager. It saves an image of a hard disk in one document or in different segments which can then be recreated later. It computes MD5 hash values and affirms the integrity of the information before closing of the documents. The outcome is an image file(s) that can be saved in a several formats.
