OpenSSL is a robust, commercial-grade, full-featured Open Source Toolkit
for the Transport Layer Security (TLS) protocol formerly known as the
Secure Sockets Layer (SSL) protocol. The protocol implementation is based
OpenSSL is descended from the SSLeay library developed by Eric A. Young
and Tim J. Hudson.

Table of Contents
=================
The OpenSSL toolkit includes:
- **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
- **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

Unix operating systems it is normally recommended to link against the
precompiled shared libraries provided by the distributor or vendor.

For Testing and Development
---------------------------
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][],
+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
+ git clone git://git.openssl.org/openssl.git
or from the GitHub mirror using
- git clone https://github.com/openssl/openssl.git
+ 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
+ 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).
