   8  DESCRIPTION
   9  -----------
  10
  11  The OpenSSL Project is a collaborative effort to develop a robust,
  12  commercial-grade, fully featured, and Open Source toolkit implementing the
  13  Transport Layer Security (TLS) protocols (including SSLv3) as well as a
  14  full-strength general purpose cryptographic library.
  15
  16  OpenSSL is descended from the SSLeay library developed by Eric A. Young
  17  and Tim J. Hudson.
  18
  19  The OpenSSL toolkit is licensed under the Apache License 2.0, which means
  20  that you are free to get and use it for commercial and non-commercial
  21  purposes as long as you fulfill its conditions.
  22
  23  OVERVIEW
  24  --------
  25
  26  The OpenSSL toolkit includes:
  27
  28  libssl (with platform specific naming):
  29      Provides the client and server-side implementations for SSLv3 and TLS.
  30
  31  libcrypto (with platform specific naming):
  32      Provides general cryptographic and X.509 support needed by SSL/TLS but
  33      not logically part of it.
  34
  35  openssl:
  36      A command line tool that can be used for:
  37         Creation of key parameters
  38         Creation of X.509 certificates, CSRs and CRLs
  39         Calculation of message digests
  40         Encryption and decryption
  41         SSL/TLS client and server tests
  42         Handling of S/MIME signed or encrypted mail
  43         And more...

  45  INSTALLATION
  46  ------------
  47
  48  See the appropriate file:

  50         NOTES.*         INSTALL addendums for different platforms
  51
  52  SUPPORT
  53  -------
  54
  55  See the OpenSSL website www.openssl.org for details on how to obtain
  56  commercial technical support. Free community support is available through the
  57  openssl-users email list (see
  58  https://www.openssl.org/community/mailinglists.html for further details).
  59
  60  If you have any problems with OpenSSL then please take the following steps
  61  first:
  62
  63     - Download the latest version from the repository
  64       to see if the problem has already been addressed
  65     - Configure with no-asm
  66     - Remove compiler optimization flags
  67
  68  If you wish to report a bug then please include the following information
  69  and create an issue on GitHub:
  70
  71     - OpenSSL version: output of 'openssl version -a'
  72     - Configuration data: output of 'perl configdata.pm --dump'
  73     - OS Name, Version, Hardware platform
  74     - Compiler Details (name, version)
  75     - Application Details (name, version)
  76     - Problem Description (steps that will reproduce the problem, if known)
  77     - Stack Traceback (if the application dumps core)
  78
  79  Just because something doesn't work the way you expect does not mean it
  80  is necessarily a bug in OpenSSL. Use the openssl-users email list for this type
  81  of query.

  88  LEGALITIES
  89  ----------
  90
  91  A number of nations restrict the use or export of cryptography. If you
  92  are potentially subject to such restrictions you should seek competent
  93  professional legal advice before attempting to develop or distribute
  94  cryptographic code.
