| 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. The OpenSSL toolkit is licensed under a dual-license (the
|
|---|
| 18 | OpenSSL license plus the SSLeay license), which means that you are free to
|
|---|
| 19 | get and use it for commercial and non-commercial purposes as long as you
|
|---|
| 20 | fulfill the conditions of both licenses.
|

|

| 22 | OVERVIEW
|
|---|
| 23 | --------
|
|---|
| 24 |
|
|---|
| 25 | The OpenSSL toolkit includes:
|
|---|
| 26 |
|
|---|
| 27 | libssl (with platform specific naming):
|
|---|
| 28 | Provides the client and server-side implementations for SSLv3 and TLS.
|
|---|
| 29 |
|
|---|
| 30 | libcrypto (with platform specific naming):
|
|---|
| 31 | Provides general cryptographic and X.509 support needed by SSL/TLS but
|
|---|
| 32 | not logically part of it.
|
|---|
| 33 |
|
|---|
| 34 | openssl:
|
|---|
| 35 | A command line tool that can be used for:
|
|---|
| 36 | Creation of key parameters
|
|---|
| 37 | Creation of X.509 certificates, CSRs and CRLs
|
|---|
| 38 | Calculation of message digests
|
|---|
| 39 | Encryption and decryption
|
|---|
| 40 | SSL/TLS client and server tests
|
|---|
| 41 | Handling of S/MIME signed or encrypted mail
|
|---|
| 42 | And more...
|
|---|

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

| 87 | LEGALITIES
|
|---|
| 88 | ----------
|
|---|
| 89 |
|
|---|
| 90 | A number of nations restrict the use or export of cryptography. If you
|
|---|
| 91 | are potentially subject to such restrictions you should seek competent
|
|---|
| 92 | professional legal advice before attempting to develop or distribute
|
|---|
| 93 | cryptographic code.
