OpenSSL is an open-source cryptographic library and SSL toolkit. The applications contained in the library help create a secure communication environment for computer networks.

Specific notes on upgrading to OpenSSL 3.0 from previous versions, as well as known issues are available on the OpenSSL wiki. Documentation Manual Pages. The manual pages for the master branch and all current stable releases are available online. OpenSSL master; OpenSSL 1.1.1; Wiki. There is a Wiki at wiki.openssl.org which is currently not.

Openssl on RHEL5 is based on openssl-0.9.8e. This article is part of the Securing Applications Collection. Download mplayer for mac 10.5. Due to the serious flaws uncovered in openssl during the lifetime of RHEL5 you should always use the latest version but at least.
OpenSSL contains an implementation of SSL and TLS protocols, meaning that most servers and HTTPS websites use its resources.
In this tutorial, learn how to find the OpenSSL version with a single command.
A command-line/terminal window.
OpenSSL installed on your system.
The openssl version command allows you to determine the version your system is currently using. This information is useful if you want to find out if a particular feature is available, verify whether a security threat affects your system, or perhaps report a bug. Type in:
The resulting data will consist of the OpenSSL version designation and the date of its initial release.
The output is clear and easy to understand. We can break down the version format to get valuable insight. Additionally, using flags can help structure the data.
The format of the version provides a lot of information. The position of the numbers represent the release type:
Major Releases – You can recognize a major release if one or both of the first two digits change. This type of release can break compatibility with previous versions. For example: 1.1.0g vs. 1.2.0
Minor Releases – A minor release changes the last number of the version designation, e.g., 1.1.0 vs. 1.1.1. These releases are likely to contain new features; however, they should not break binary compatibility. You do not need to recompile applications to benefit from them.
Letter Releases – The release designation in our example 1.1.0g contains bug and security fixes exclusively. No new features were added.
Note: The next planned version of OpenSSL is 3.0.0. Once the new version is released, the versioning scheme is going to change to a more contemporary format: MAJOR.MINOR.PATCH
By using a general flag –help we can see an overview of all valid options for openssl version.
There are eight (8) valid options that allow you to narrow your search. The option that provides the most comprehensive set of information is:
This option is convenient, especially when troubleshooting or composing a bug report.
The OPENSSLDIR line is especially interesting, as it will tell you where OpenSSL will look for its configurations and certificates. You can print out that specific line by using the following command:
In this example, the configuration files and certificates are located at /usr/lib/ssl
Now you have learned how to check the OpenSSL version.
You should now understand how to interpret that data. And how it can be used to improve server security, troubleshoot or submit a bug request.
The flags presented in the article provided you with the necessary tools to help you make an informed decision and administer your system effectively.

Open Source toolkit implementing the Secure Sockets Layer.

Development

The OpenSSL Project is a collaborative effort to develop a robust, commercial-grade, full-featured, and Open Source toolkit implementing the Secure Sockets Layer (SSL v2/v3) and Transport Layer Security (TLS v1) protocols as well as a full-strength general purpose cryptography library. The project is managed by a worldwide community of volunteers that use the Internet to communicate, plan, and develop the OpenSSL toolkit and its related documentation. OpenSSL is based on the excellent SSLeay library developed by Eric A. Young and Tim J. Hudson. The OpenSSL toolkit is licensed under an Apache-style licence, which basically means that you are free to get and use it for commercial and non-commercial purposes subject to some simple license conditions.
