| 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. |
| 21 | |
| 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... |
| 43 | |
| 44 | INSTALLATION |
| 45 | ------------ |
| 46 | |
| 47 | See the appropriate file: |
| 48 | INSTALL Linux, Unix, Windows, OpenVMS, ... |
| 49 | NOTES.* INSTALL addendums for different platforms |
| 50 | |
| 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. |
