DESCRIPTION
|
|
|
|
|
-----------
|
|
|
|
|
|
|
|
|
|
The OpenSSL Project is a collaborative effort to develop a robust,
|
|
|
|
|
commercial-grade, fully featured, and Open Source toolkit implementing the
|
2018-09-13 19:18:07 +00:00
|
|
|
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
|
2000-01-10 06:22:05 +00:00
|
|
|
and Tim J. Hudson. The OpenSSL toolkit is licensed under a dual-license (the
|
2015-12-03 17:22:58 +00:00
|
|
|
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.

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

The OpenSSL toolkit includes:
|
|
|
|
|
|
2018-09-13 19:18:07 +00:00
|
|
|
libssl (with platform specific naming):
|
2015-12-03 17:22:58 +00:00
|
|
|
Provides the client and server-side implementations for SSLv3 and TLS.
|
2000-01-10 06:22:05 +00:00
|
|
|
|
2018-09-13 19:18:07 +00:00
|
|
|
libcrypto (with platform specific naming):
|
2015-12-03 17:22:58 +00:00
|
|
|
Provides general cryptographic and X.509 support needed by SSL/TLS but
|
|
|
|
|
not logically part of it.

|
first:
|
|
|
|
|
|

|
|
to see if the problem has already been addressed
|
2017-01-26 18:32:12 +00:00
|
|
|
- Configure with no-asm
|
2018-09-13 19:18:07 +00:00
|
|
|
- Remove compiler optimization flags
|
2000-01-10 06:22:05 +00:00

Just because something doesn't work the way you expect does not mean it
|
2018-09-13 19:18:07 +00:00
|
|
|
is necessarily a bug in OpenSSL. Use the openssl-users email list for this type
|
|
|
|
|
of query.

A number of nations restrict the use or export of cryptography. If you
|
|
|
|
|
are potentially subject to such restrictions you should seek competent
|
|
|
|
|
professional legal advice before attempting to develop or distribute
|
|
|
|
|
cryptographic code.
