The Role of a Hash By definition, forensic copies are exact, bit-for-bit duplicates of the original. To verify this, we can use a hash function to produce a type of “checksum” of the source data. As each bit of the original media is read and copied, that bit is also entered into a hashing algorithm.. Hashing vs Encryption — The Big Players of the Cyber Security World ... We can't replace hashing with encryption, or vice versa, because they are ... algorithm, illustrates the simple concept that encrypted data is reversible.. Hashes play a role in security systems where they're used to ensure that transmitted messages have not been tampered with. The sender generates a hash of ....
