MD5 Info: In cryptography, MD5 (Message-Digest algorithm 5) is a widely used cryptographic hash function with a 128-bit hash value. As an Internet standard, MD5 has been employed in a wide variety of security applications, and is also commonly used to check the integrity of files. An MD5 hash is typically expressed as a 32-digit hexadecimal number.

HASH Info: A cryptographic hash function is a deterministic procedure that takes an arbitrary block of data and returns a fixed-size bit string, the hash value, such that an accidental or intentional change to the data will change the hash value. The ideal cryptographic hash function has four main properties: easy to compute the hash value for any given message, infeasible to find a message that has a given hash, infeasible to modify a message without changing its hash and infeasible to find two different strings with the same hash.
