Because the hash creates just a fingerprint of the message which cannot be reversed and it is also very difficult to create a second message with the same hash.<br \/>\nA hash by itself does not provide Authentication. It only provides a weak form or integrity. It would be possible for an attacker to perform a Man-In-The-Middle attack where both the hash and the digest could be changed without the receiver knowing it.<br \/>\nA hash combined with your session key will produce a Message Authentication Code (MAC) which will provide you with both authentication of the source and integrity. It is sometimes referred to as a Keyed Hash. A hash encrypted with the sender private key produce a Digital Signature which provide authentication, but not the hash by itself. Hashing functions by themselves such as MD5, SHA1, SHA2, SHA-3 does not provide authentication.<br \/>\nSource: HARRIS, Shon, All-In-One CISSP Certification Exam Guide, McGraw-Hill\/Osborne, 2001, Page 548<\/div>\n<p><\/strong><\/span> <\/div>\n","protected":false},"excerpt":{"rendered":"<p>What is NOT true about a one-way hashing function?
