Despite growing adoption of TLS, a significant fraction of TCP
traffic on the Internet remains unencrypted. The persistence of
unencrypted traffic can be attributed to at least two factors.
First, some legacy protocols lack a signaling mechanism (such as a
STARTTLS command) by which to convey support for encryption, thus
making incremental deployment impossible. Second, legacy
applications themselves cannot always be upgraded and therefore
require a way to implement encryption transparently entirely within
the transport layer. The TCP Encryption Negotiation Option (TCP-ENO)
addresses both of these problems through a new TCP option kind
providing out-of-band, fully backward-compatible negotiation of
encryption.
