- 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 optimization 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'
- - Configuration data: output of 'perl configdata.pm --dump'
- - 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.
- HOW TO CONTRIBUTE TO OpenSSL
- ----------------------------
- See CONTRIBUTING
- 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.
