+synopsis: "Transport Layer Security purely in OCaml - Eio"
+description: """
+Transport Layer Security (TLS) is probably the most widely deployed security
+protocol on the Internet. It provides communication privacy to prevent
+eavesdropping, tampering, and message forgery. Furthermore, it optionally
+provides authentication of the involved endpoints. TLS is commonly deployed for
+securing web services ([HTTPS](http://tools.ietf.org/html/rfc2818)), emails,
+virtual private networks, and wireless networks.
+
+TLS uses asymmetric cryptography to exchange a symmetric key, and optionally
+authenticate (using X.509) either or both endpoints. It provides algorithmic
+agility, which means that the key exchange method, symmetric encryption
+algorithm, and hash algorithm are negotiated.
