     "This library provides a C99 implementation of SSL/TLS.  It is designed to
be familiar to users of the widely-used POSIX I/O APIs.  It supports blocking,
non-blocking, and full-duplex I/O.  There are no locks or mutexes.

As it can be difficult to keep track of which encryption algorithms and
protocols are best to use, s2n-tls features a simple API to use the latest
default set of preferences.  Remaining on a specific version for backwards
compatibility is also supported.")
