The protocol implementation is based +on a full-strength general purpose cryptographic library, which can also +be used stand-alone. OpenSSL is descended from the SSLeay library developed by Eric A. Young and Tim J. Hudson. -The OpenSSL toolkit is licensed under the Apache License 2.0, which means -that you are free to get and use it for commercial and non-commercial -purposes as long as you fulfill its conditions. +The official Home Page of the OpenSSL Project is [www.openssl.org][]. + + +Table of Contents +================= + + - [Overview](#overview) + - [Download](#download) + - [Build and Install](#build-and-install) + - [Documentation](#documentation) + - [License](#license) + - [Support](#support) + - [Contributing](#contributing) + - [Legalities](#legalities) Overview ======== The OpenSSL toolkit includes: - * **libssl** - Provides the client and server-side implementations for SSLv3 and TLS. +- **libssl** + an implementation of all TLS protocol versions up to TLSv1.3 ([RFC 8446][]). + +- **libcrypto** + a full-strength general purpose cryptographic library. It constitutes the + basis of the TLS implementation, but can also be used independently. + +- **openssl** + the OpenSSL command line tool, a swiss army knife for cryptographic tasks, + testing and analyzing. It 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... + +Download +======== - * **libcrypto:** - Provides general cryptographic and X.509 support needed by SSL/TLS but - not logically part of it. +For Production Use +------------------ - * **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... +Source code tarballs of the official releases can be downloaded from +[www.openssl.org/source](https://www.openssl.org/source). +The OpenSSL project does not distribute the toolkit in binary form. -Installation -============ +However, for a large variety of operating systems precompiled versions +of the OpenSSL toolkit are available. In particular on Linux and other +Unix operating systems it is normally recommended to link against the +precompiled shared libraries provided by the distributor or vendor. -See the appropriate file: - * [INSTALL](INSTALL): General installation instructions for all platforms - * Additional instructions for specific platforms - * [NOTES.ANDROID](NOTES.ANDROID) - * [NOTES.DJGPP](NOTES.DJGPP) - * [NOTES.PERL](NOTES.PERL) - * [NOTES.UNIX](NOTES.UNIX) - * [NOTES.VALGRIND](NOTES.VALGRIND) - * [NOTES.VMS](NOTES.VMS) - * [NOTES.WIN](NOTES.WIN) +For Testing and Development +--------------------------- -Support +Although testing and development could in theory also be done using +the source tarballs, having a local copy of the git repository with +the entire project history gives you much more insight into the +code base. + +The official OpenSSL Git Repository is located at [git.openssl.org][]. +There is a GitHub mirror of the repository at [github.com/openssl/openssl][], +which is updated automatically from the former on every commit. + +A local copy of the Git Repository can be obtained by cloning it from +the original OpenSSL repository using + + git clone git://git.openssl.org/openssl.git + +or from the GitHub mirror using + + git clone https://github.com/openssl/openssl.git + +If you intend to contribute to OpenSSL, either to fix bugs or contribute +new features, you need to fork the OpenSSL repository openssl/openssl on +GitHub and clone your public fork instead. + + git clone https://github.com/yourname/openssl.git + +This is necessary, because all development of OpenSSL nowadays is done via +GitHub pull requests. For more details, see [Contributing](#contributing). + + +Build and Install +================= + +After obtaining the Source, have a look at the [INSTALL](INSTALL.md) file for +detailed instructions about building and installing OpenSSL.
