A hash value is a common feature used in forensic analysis as well as the cryptographic world. Which gives us k values. The ability to force md5 hash collisions has been a reality for more than a decade, although there is a general consensus that hash collisions are of minimal impact to the

Generating a hash value of the evidence media before commencing analysis of the evidence media, it is mandatory to ensure that integrity of evidence is preserved.

Hash(message 1) = hash(message 2).in computer forensics hash functions are important because they provide a means of identifying and classifying electronic evidence. Md5 and sha hash function is used in digital forensic tools to calculate and verify that a data set has not been altered, due to the application of various evidence collection and analysis tools. A hash value is a result of a calculation that can be performed on a string of text, electronic file or entire hard drives contents. This fingerprint allows us to verify that the image we created, and are working from, is indeed an identical copy of the original evidence.
