| 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 a dual-license (the | |
| OpenSSL license plus the SSLeay license), which means that you are free to | |
| get and use it for commercial and non-commercial purposes as long as you | |
| fulfill the conditions of both licenses. | |
| 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 optimisation 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' | |
| - Any "Configure" options that you selected during compilation of the | |
| library if applicable (see INSTALL) | |
| - 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. |
