|
|
Packit |
c4476c |
The OpenSSL Project is a collaborative effort to develop a robust,
|
|
Packit |
c4476c |
commercial-grade, fully featured, and Open Source toolkit implementing the
|
|
Packit |
c4476c |
Transport Layer Security (TLS) protocols (including SSLv3) as well as a
|
|
Packit |
c4476c |
full-strength general purpose cryptographic library.
|
|
Packit |
c4476c |
|
|
Packit |
c4476c |
OpenSSL is descended from the SSLeay library developed by Eric A. Young
|
|
Packit |
c4476c |
and Tim J. Hudson. The OpenSSL toolkit is licensed under a dual-license (the
|
|
Packit |
c4476c |
OpenSSL license plus the SSLeay license), which means that you are free to
|
|
Packit |
c4476c |
get and use it for commercial and non-commercial purposes as long as you
|
|
Packit |
c4476c |
fulfill the conditions of both licenses.

Packit |
c4476c |
libssl (with platform specific naming):
|
|
Packit |
c4476c |
Provides the client and server-side implementations for SSLv3 and TLS.
|
|
Packit |
c4476c |
|
|
Packit |
c4476c |
libcrypto (with platform specific naming):
|
|
Packit |
c4476c |
Provides general cryptographic and X.509 support needed by SSL/TLS but
|
|
Packit |
c4476c |
not logically part of it.
|
|
Packit |
c4476c |
|
|
Packit |
c4476c |
openssl:
|
|
Packit |
c4476c |
A command line tool that can be used for:
|
|
Packit |
c4476c |
Creation of key parameters
|
|
Packit |
c4476c |
Creation of X.509 certificates, CSRs and CRLs
|
|

If you have any problems with OpenSSL then please take the following steps
|
|
Packit |
c4476c |
first:
|
|
Packit |
c4476c |
|
|
Packit |
c4476c |
- Download the latest version from the repository
|
|
Packit |
c4476c |
to see if the problem has already been addressed
|
|
Packit |
c4476c |
- Configure with no-asm
|
|
Packit |
c4476c |
- Remove compiler optimization flags
|
|
Packit |
c4476c |
|
|
Packit |
c4476c |
If you wish to report a bug then please include the following information
|
|
Packit |
c4476c |
and create an issue on GitHub:
|
|
Packit |
c4476c |
|
|
Packit |
c4476c |
- OpenSSL version: output of 'openssl version -a'
|
|
Packit |
c4476c |
- Configuration data: output of 'perl configdata.pm --dump'
|
|
Packit |
c4476c |
- OS Name, Version, Hardware platform
|
|
Packit |
c4476c |
- Compiler Details (name, version)
|
|
Packit |
c4476c |
- Application Details (name, version)
|
|
Packit |
c4476c |
- Problem Description (steps that will reproduce the problem, if known)
|
|
Packit |
c4476c |
- Stack Traceback (if the application dumps core)

Just because something doesn't work the way you expect does not mean it
|
|
Packit |
c4476c |
is necessarily a bug in OpenSSL. Use the openssl-users email list for this type
|
|
Packit |
c4476c |
of query.

c4476c |
----------
|
|
Packit |
c4476c |
|
|
Packit |
c4476c |
A number of nations restrict the use or export of cryptography. If you
|
|
Packit |
c4476c |
are potentially subject to such restrictions you should seek competent
|
|
Packit |
c4476c |
professional legal advice before attempting to develop or distribute
|
|
Packit |
c4476c |
cryptographic code.
