Hashing algorithms

A hashing algorithm takes the data from a document and generates a hexadecimal value from that input. If you take the same data and hash it with the same algorithm it will generate the same hash. In the Security + exam, the hashing algorithms are SHA-1, which is 160 bits, and MD5, which is 128 bits. Hashing is a one-way function to ensure that the integrity of the data is intact.
