The OpenSSL Project is a collaborative effort to develop a robust,
|
1998-12-22 23:04:48 +08:00
|
|
|
commercial-grade, fully featured, and Open Source toolkit implementing the
|
2016-06-02 18:01:32 +08:00
|
|
|
Transport Layer Security (TLS) protocols (including SSLv3) as well as a
|
|
|
|
full-strength general purpose cryptographic library.

OpenSSL is descended from the SSLeay library developed by Eric A. Young
|
1999-03-06 21:35:14 +08:00
|
|
|
and Tim J. Hudson. The OpenSSL toolkit is licensed under a dual-license (the
|
2015-10-30 00:06:06 +08:00
|
|
|
OpenSSL license plus the SSLeay license), which means that you are free to
|
|
|
|
get and use it for commercial and non-commercial purposes as long as you
|
|
|
|
fulfill the conditions of both licenses.

Just because something doesn't work the way you expect does not mean it
|
2016-06-02 18:01:32 +08:00
|
|
|
is necessarily a bug in OpenSSL. Use the openssl-users email list for this type
|
|

of query.

----------
|
|
|
|

2016-10-26 23:48:43 +08:00
|
|
|
A number of nations restrict the use or export of cryptography. If you
|
2016-10-13 03:49:06 +08:00
|
|
|
are potentially subject to such restrictions you should seek competent
|
|
|
|
professional legal advice before attempting to develop or distribute
|
|
|
|
cryptographic code.
