 DESCRIPTION

 -----------



 The OpenSSL Project is a collaborative effort to develop a robust,

 commercial-grade, fully featured, and Open Source toolkit implementing the

 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

 and Tim J. Hudson.



 The OpenSSL toolkit is licensed under the Apache License 2.0, which means

 that you are free to get and use it for commercial and non-commercial

 purposes as long as you fulfill its conditions.



 OVERVIEW

 --------



 The OpenSSL toolkit includes:



 libssl (with platform specific naming):

     Provides the client and server-side implementations for SSLv3 and TLS.



 libcrypto (with platform specific naming):

     Provides general cryptographic and X.509 support needed by SSL/TLS but

     not logically part of it.



 openssl:

     A command line tool that can be used for:

        Creation of key parameters

        Creation of X.509 certificates, CSRs and CRLs

        Calculation of message digests

        Encryption and decryption

        SSL/TLS client and server tests

        Handling of S/MIME signed or encrypted mail

        And more...



 INSTALLATION

 ------------



 See the appropriate file:

        INSTALL         Linux, Unix, Windows, OpenVMS, ...

        NOTES.*         INSTALL addendums for different platforms



 SUPPORT

 -------



 See the OpenSSL website www.openssl.org for details on how to obtain

 commercial technical support. Free community support is available through the

 openssl-users email list (see

 https://www.openssl.org/community/mailinglists.html for further details).



 If you have any problems with OpenSSL then please take the following steps

 first:



    - Download the latest version from the repository

      to see if the problem has already been addressed

    - Configure with no-asm

    - Remove compiler optimization flags



 If you wish to report a bug then please include the following information

 and create an issue on GitHub:



    - OpenSSL version: output of 'openssl version -a'

    - Configuration data: output of 'perl configdata.pm --dump'

    - OS Name, Version, Hardware platform

    - Compiler Details (name, version)

    - Application Details (name, version)

    - Problem Description (steps that will reproduce the problem, if known)

    - Stack Traceback (if the application dumps core)



 Just because something doesn't work the way you expect does not mean it

 is necessarily a bug in OpenSSL. Use the openssl-users email list for this type

 of query.

 LEGALITIES

 ----------



 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.
