MD5—Message Digest 5. An algorithm that is used to create digital signatures. MD5 is a one-way hash 
function, meaning that it takes a message and converts it into a fixed string of digits, also called a 
message digest. When a one-way hash function is used, a calculated message digest is compared against 
the received message digest to verify that the message has not been tampered with. This comparison is 
called a hashcheck.
