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), 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.
opam install tls will install this library.
