How does hashing work?
What will be an ideal response?
Hashing is the mathematical process that produces the message digest or "hash." Hash functions are essentially checksum algorithms. The message is treated as a large number, and it subjects to mathematical transformations that result in the creation of hash. Data is passed to a hash function, and it outputs a fixed-sized hash. Hash functions have the mathematical properties such that passing identical data into the hash function twice always produces identical results. Also, the original message cannot be recreated from the hash. To check for potential tampering, the message recipient rehashes the full message in hand and compares the result with the hash created by the sender. If the hash values do not match, the message has been altered.
