In this article, we’ll explain how to install OpenSSL 1.1.1i in CentOS 8.

Linux

OpenSSL is a robust, commercial-grade, and full-featured toolkit for the Transport Layer Security (TLS) and Secure Sockets Layer (SSL) protocols. OpenSSL is a software library for applications that secure communications over computer networks against eavesdropping or need to identify the party at the other end.

OpenSSL is licensed under an Apache-style license, which means that you are free to get and use it for commercial and non-commercial purposes subject to some simple license conditions. For a list of vulnerabilities, and the releases in which they were found and fixes, see our Vulnerabilities page.

Prerequisites

  1. This how-to will step you through installing OpenSSL on Windows with Cygwin. OpenSSL is a very useful open-source command-line toolkit for working with SSL/TLS certificates and certificate signing requests (CSRs). With OpenSSL you can easily.
  2. Install development tool. We need to install a development tool and few dependencies to install OpenSSL # dnf group install ‘Development Tools’ 3. Install dependencies # dnf install perl-core zlib-devel -y. Download OpenSSL 1.1.1i. We will download the latest stable version is the 1.1.1 series.
  3. OpenSSL is a cryptographic library for applications to do secure communications over computer networks. Let’s see how to install OpenSSL in Windows 10 machine. Install OpenSSL in Windows 10 64-bit Operating System. Below are the steps to install OpenSSL in windows 10 64-bit OS. Download the windows binary.
  • A CentOS 8 installed dedicated server or KVM VPS.
  • A root user access or normal user with administrative privileges.

1. Keep the server up to date

Always keep the server up to date the security purpose.

# dnf update -y

Heartbleed security vulnerability - OpenSSL 1.0.1 - See here. Install OpenSSL on a windows machine. To perform certain cryptographic operations (creation of a private key, generation of a CSR, conversion of a certificate.) on a Windows computer we can use the OpenSSL tool.

2. Install development tool

We need to install a development tool and few dependencies to install OpenSSL

# dnf group install ‘Development Tools’

3. Install dependencies

# dnf install perl-core zlib-devel -y

4. Download OpenSSL 1.1.1i

We will download the latest stable version is the 1.1.1 series. This is also our Long Term Support (LTS) version, supported until 11th September 2023.

# cd /usr/local/src/

# wget https://www.openssl.org/source/openssl-1.1.1i.tar.gz

Now, extract the tar file

Installing Openssl On Windows 10

# tar -xzvf openssl-1.1.1i.tar.gz

5. Configure and build

Navigate to the extracted directory and configure, build, test and install OpenSSL in the default location /usr/local/ssl.

# cd openssl-1.1.1i

Configure it with PATH

# ./config –prefix=/usr/local/ssl –openssldir=/usr/local/ssl shared zlib

Output:

Now, build

# make

# make test

# make install

6. Configure it shared libraries.

Once we have successfully installed OpenSSL, configure it shared libraries.

Naviagate to the /etc/ld.so.conf.d directory and create a configuration file.

# cd /etc/ld.so.conf.d/

# vi openssl-1.1.1i.conf

Add the following path in the config file

/usr/local/ssl/lib

Save and exit

Reload the dynamic link

Installing Openssl On Linux

# ldconfig -v

7. Configure OpenSSL Binary

Now, we are going to insert the binary of our new version of OpenSSL /usr/local/ssl/bin/openssl and replace the default openssl file.

First, take a backup of existed openssl file.

# mv /bin/openssl /bin/openssl.backup

Create new environment files for OpenSSL

# vi /etc/profile.d/openssl.sh

and add the following lines

OPENSSL_PATH=”/usr/local/ssl/bin”
export OPENSSL_PATH
PATH=$PATH:$OPENSSL_PATH
export PATH

Save & exit

Make the newly created file executable

# chmod +x /etc/profile.d/openssl.sh

Reload the new OpenSSL environment file and check the default PATH

# source /etc/profile.d/openssl.sh
# echo $PATH

Now, let’s verify the installation and version of the OpenSSL

# which openssl
# openssl version -a

Output will be similar like:

OpenSSL 1.1.1i 8 Dec 2020
built on: Sun Jan 10 03:58:36 2021 UTC
platform: linux-x86_64
options: bn(64,64) rc4(16x,int) des(int) idea(int) blowfish(ptr)

OPENSSLDIR: “/usr/local/ssl”
ENGINESDIR: “/usr/local/ssl/lib/engines-1.1”
Seeding source: os-specific

That’s it, the installation has been completed successfully.

In this article, we’ve learned how to install OpenSSL 1.1.1i in CentOS 8.

Installing Openssl On Windows Server 2016

In a recent tutorial, I explained how to generate secure self-signed server and client certificates with OpenSSL. Today, I thought it would be helpful to focus on manually installing OpenSSL on Windows, Linux, and macOS.

Installing OpenSSL can be tricky, and there are a few different ways to do this. To simplify your life, I have listed the method for each OS that I believe is the most straightforward.

Installing OpenSSL on Windows

This tutorial is mostly for Windows 10 users, since OpenSSL does not ship with Windows 10 by default.

OpenSSL can be installed with Chocolatey, which can be easily deployed in an organization or installed for a single user. It is also be a great tool for patch management.

Once Chocolatey has been installed, run the following command line:

Installing OpenSSL on Linux

Arch Linux

Installing Openssl

By default, OpenSSL is already included in Arch Linux. If this is not the case with your instance, then run the following command line:

Installing Openssl Ubuntu

CentOS / Red Hat

By default, OpenSSL is already included in CentOS. If this is not the case with your instance, then run the following command line:

Ubuntu

By default, OpenSSL is already included in Ubuntu. If this is not the case with your instance, then run the following command line:

Installing OpenSSL on macOS

Installing Openssl Linux

By default, OpenSSL is already installed in macOS. However, your version may be outdated. If so, then you can install the latest version with Homebrew. After installing Homebrew, simply run the following command line:

Advanced: Self Compile

Installing Openssl

Installing Openssl Solaris

Some people do not trust the pre-compiled binaries available on the package sources listed above. If you feel this way, then OpenSSL can be compiled from sources by following the steps listed here: https://github.com/openssl/openssl. However, you should be aware that this is a complex process and requires significant technical skill.

Installing Openssl-1.1.1j
