BearSSL - development files

 It aims at offering the following features:
 .
 Be correct and secure. In particular, insecure protocol versions and choices
 of algorithms are not supported, by design; cryptographic algorithm
 implementations are constant-time by default.
 .
 Be small, both in RAM and code footprint. For instance, a minimal server
 implementation may fit in about 20 kilobytes of compiled code
 and 25 kilobytes of RAM.
 .
 Be highly portable. BearSSL targets not only “big” operating systems like
 Linux and Windows, but also small embedded systems and even special contexts
 like bootstrap code.
 .
 Be feature-rich and extensible. SSL/TLS has many defined cipher suites and
 extensions; BearSSL should implement most of them, and allow extra algorithm
 implementations to be added afterwards, possibly from third parties.
