Hashing Tools are Vital-Week 4: Hashing Tools are Vital to Computer Forensics (Required/Graded)

Hashing is when a mathematical algorithm is applied to digital data and it is critical to forensic evidence collection and validation. Some of the most commonly used hashes are the Message Digest 5 hash (MD5) and Secure Hashing Algorithm (SHA-1). The MD5 hash is a 128-bit hexadecimal value, and the SHA-1 hash is a 160-bit hexadecimal value. A hexadecimal number contains all of the numbers 0-9 and letters from A-F, with A representing the number 10 and F representing the number 15 (0-F is 16 digits). Here is an example of an MD5 hash: 2FBB61AF3038AA31DC29977FF077344A. There are other hashes used for verification including SHA-256, SHA-384, and SHA 512, which are 256-bit, 384-bit, and 512-bit hexadecimal values.
