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.
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 command compiles all the information contained under the individual flags into a single output.
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.

OpenSSL provides different features and tools for SSL/TLS related operations. s_lient is a tool used to connect, check, list HTTPS, TLS/SSL related information. Simply we can check remote TLS/SSL connection with s_client . In these tutorials, we will look at different use cases of s_client .Check TLS/SSL Of Website
The basic and most popular use case for s_client is just connecting remote TLS/SSL website. We will provide the web site with the HTTPS port number. In this example we will connect to the poftut.com .Check TLS/SSL Of Website with Specifying Certificate Authority
If the web site certificates are created in house or the web browsers or Global Certificate Authorities do not sign the certificate of the remote site we can provide the signing certificate or Certificate authority. We will use -CAfile by providing the Certificate Authority File.Connect Smtp and Upgrade To TLS
We can use s_client to test SMTP protocol and port and then upgrade to TLS connection. We will use -starttls smtp command. We will use the following command.Connect HTTPS Site Disabling SSL2
HTTPS or SSL/TLS have different subversions. We can enable or disable the usage of some of them. In this example, we will disable SSLv2 connection with the following command.Connect HTTPS Only TLS1 or TLS2
Like the previous example, we can specify the encryption version. In this example, we will only enable TLS1 or TLS2 with the -tls1_2 .Specify Cipher or Encryption Type
We can specify the cipher with the -cipher option like below.Connect HTTPS Only RC4-SHAOpenssl Failed To Enumerate Slots Software
We can also specify the hash algorithm of the encryption protocol. In this example, we will only enable RC4-SHA hash algorithm for SSL/TLS connection. We will use -cipher RC4-SHA . All other encryption and Cipher types will be denied and the connection will be closed.Openssl Failed To Enumerate Slots ListDebug SSL/TLS To The HTTPSOpenssl Pkcs11 Failed To Enumerate Slots
While a SSL/TLS connection is made there is a lot of operation under the hood. If we have some problems or we need detailed information about the SSL/TLS initialization we can use -tlsextdebug option like below.
