TLS-1.3

TLS-1.3 is an internet encryption protocol.
"TLS" stands for "transport layer security".
Such encryption was formerly called "SSL" (secure sockets layer).
TLS-1.3 was developed at the behest of the U.S. National Security Agency (NSA),
as was its predecessor-- TLS-1.2.
TLS-1.3 is only marginally better than TLS-1.2,
and TLS-1.2 is only marginally better than its predecessor TLS-1.1.

The NSA's real and classified purpose for creating these new encryption protocols
is not to make the encryption stronger, but to create incompatibility with older browsers
that have a javascript-disabling option and a stylesheet-disabling option.
TLS-1.3 especially serves to create incompatibility with the publicly-available
Opera version-12 browser, which is compatible with TLS-1.2.
