Shane Lontis f552d90045 Add Serializers for EC Provide EC serializers for text, pem and der. EC parameters use ANS1 'CHOICE' - which means they are more embedded than other parameters used by other KEY types (which normally have a SEQUENCE at the top level). For this reason the ANS1_STRING type that was being passed around has been changed to a void so that the code can still be shared with EC. The EC serializer only supports named curves currently. NOTE the serializer code assumes PKCS8 format - if the older encode methods are needed they will need to be added in another PR. (Probably when deserialization is considered). EVP_PKEY_key_fromdata_init was changed from using a keypair selection to all bits of a key. A side effect of this was that the very restrictive checks in the ecx code needed to be relaxed as it was assuming all selection flags were non optional. As this is not the case for any other key the code has been modified. Fixed a bug in legacy_ctrl_str_to_params() - "ecdh_cofactor_mode" was being incorrectly converted to the wrong keyname.

Welcome to the OpenSSL Project

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 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 official Home Page of the OpenSSL Project is www.openssl.org.

Overview

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 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

For Production Use

Source code tarballs of the official releases can be downloaded from www.openssl.org/source. The OpenSSL project does not distribute the toolkit in binary form.

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.

For Testing and Development

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.

Build and Install

After obtaining the Source, have a look at the INSTALL file for detailed instructions about building and installing OpenSSL. For some platforms, the installation instructions are amended by a platform specific document.

Documentation

Manual Pages

The manual pages for the master branch and all current stable releases are available online.

Wiki

There is a Wiki at wiki.openssl.org which is currently not very active. It contains a lot of useful information, not all of which is up to date.

License

OpenSSL 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.

See the LICENSE file for more details.

Support

There are various ways to get in touch. The correct channel depends on your requirement. see the SUPPORT file for more details.

Contributing

If you are interested and willing to contribute to the OpenSSL project, please take a look at the CONTRIBUTING file.

Since 2016, development takes place in public on the GitHub open source platform. The OpenSSL Project Pages at openssl.github.io are a valuable source of information if you want to get familiar with our development process on GitHub.

Legalities

A number of nations restrict the use or export of cryptography. If you are potentially subject to such restrictions you should seek legal advice before attempting to develop or distribute cryptographic code.
