SUMMARY = "BearSSL is an implementation of the SSL/TLS protocol (RFC 5246) written in C"
DESCRIPTION = "BearSSL is an implementation of the SSL/TLS protocol (RFC \
5246) written in C. 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."
