Detailed explanation-1: -A cryptographic checksum is based on hash functions that provide hash values–also known as hash codes–for every file. The cryptographic hash function takes an input and produces a fixed-length sequence of numbers and letters. The checksum is of the same length, regardless of the original file’s size.

Detailed explanation-2: -A hash function is a versatile one-way cryptographic algorithm that maps an input of any size to a unique output of a fixed length of bits. The resulting output, which is known as a hash digest, hash value, or hash code, is the resulting unique identifier we mentioned earlier.

Detailed explanation-3: -Hashing algorithms are just as abundant as encryption algorithms, but there are a few that are used more often than others. Some common hashing algorithms include MD5, SHA-1, SHA-2, NTLM, and LANMAN. MD5: This is the fifth version of the Message Digest algorithm. MD5 creates 128-bit outputs.

Detailed explanation-4: -The generic HashSet<T> class is an unordered collection for containing unique elements. A hash function is an algorithm that returns a numeric hash code based on a key. The key is the value of some property of the object being stored. A hash function must always return the same hash code for the same key.
