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.

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.
