1055714Skris
1155714Skris The OpenSSL Project is a collaborative effort to develop a robust,
1255714Skris commercial-grade, fully featured, and Open Source toolkit implementing the
13291719Sjkim Secure Sockets Layer (SSLv3) and Transport Layer Security (TLS) protocols as
14291719Sjkim well as a full-strength general purpose cryptograpic library. The project is
15291719Sjkim managed by a worldwide community of volunteers that use the Internet to
16291719Sjkim communicate, plan, and develop the OpenSSL toolkit and its related
17291719Sjkim documentation.
1855714Skris
19291719Sjkim OpenSSL is descended from the SSLeay library developed by Eric A. Young
2055714Skris and Tim J. Hudson.  The OpenSSL toolkit is licensed under a dual-license (the
21291719Sjkim OpenSSL license plus the SSLeay license), which means that you are free to
22291719Sjkim get and use it for commercial and non-commercial purposes as long as you
23291719Sjkim fulfill the conditions of both licenses.

3355714Skris libcrypto.a:
34291719Sjkim     Provides general cryptographic and X.509 support needed by SSL/TLS but
35291719Sjkim     not logically part of it.
3655714Skris
37160814Ssimon openssl:
3859191Skris     A command line tool that can be used for:
