'''Protocol encryption''' ('''PE'''), '''message stream encryption''' ('''MSE''') or '''protocol header encrypt''' ('''PHE'''){{efn|Usually referred to as the more proper ''protocol header encryption''.}} are related features of some [[peer-to-peer]] [[file-sharing]] [[Comparison of file sharing applications|clients]], including [[BitTorrent client]]s. They attempt to enhance privacy and confidentiality. In addition, they attempt to make traffic harder to identify by third parties including [[internet service provider]]s (ISPs).

MSE/PE is implemented in [[BitComet]], [[BitTornado]], [[Deluge (software)|Deluge]], [[Flashget]], [[KTorrent]], [[libtorrent]] (used by various BitTorrent clients, not limited toincluding [[QBittorrent|QBitTorrent]]), [[BitTorrent client|Mainline]], [[µTorrent]], [[qBittorrent]], [[rTorrent]], [[Transmission (BitTorrent client)|Transmission]], [[Tixati]] and [[Vuze]]. PHE was implemented in old versions of BitComet. Similar protocol [[obfuscation]] is supported in up-to-date versions of some other (non-BitTorrent) systems including [[eMule]].<ref>{{cite web|url=http://www.emule-project.net/home/perl/help.cgi?l=1&rm=show_topic&topic_id=848|title=eMule protocol obfuscation (encryption)|publisher=emule-project.net|date=2006-09-16|accessdate=2010-03-11}}</ref>
