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.
