			September 11
			* most email is sent in plaintext
			* SMTP is a store and forward protocol
			* Hops may use point-to-point encryption
			* Analog days: passing notes in class
			* End to End Encryption
			** PGP
			*** pretty good privacy
			*** encrypt or digitally sign mail
			** S/MIME
			** attacker doesn't know at which point to get to message
			** wouldn't know how to unencrypt unless they had key
			*point to point encryption: SSL/TLS
			** can attack at many points through mail transfer
			*asymmetric - a public key and a private key
			** two keys, one is public one is private
			*** can use either to encrypt message

			[[Sending message
			]]\|Hi Bob!\| -> hash function (MD5) ->\|0110110\|->Encrypt ->Signature
			signature Private Key

			[[Receiving Message]]
			\|Hi Bob!\|-sh>md5sum msg.txt->\|0110110\|->Decrypt -> Signature value
			Signature
			Public Key

			* if anything changed in transit, it would change hash function value and would let you know that the message integrity has failed
			* by not encrypting we cannot ensure integrity of communications
			* trace route a couple of your packets
			* IETF = ISO
			** RFC
			*** SMTP
			*** CMS
			** OpenPGP
			*** GPG -> free license
			*** PGP (Pretty good privacy)
