Why we want to use MD5?

Actually MD5 algorithm take file of any size, which is a message to the algorithm. Best thing or feature of the MD5 algorithm is, if a message change its single byte, algorithm will produce totally different digest or hash.

Simply, you can call MD5 as the fingerprint of a particular message or file.

MD5 ensures that, the file transmitting from point A to point B arrives intact and without any distortion. 

The complete process is handled by MD5 algorithm by generating hash string at point A and also generate the hash string which we refer as checksum at point B. 

And check files integrity whether both the strings generated by MD5 are same or not.
