Best Guide to Install OpenSSL 3 on Ubuntu 20.04

In this guide, you will learn to Install OpenSSL 3 on Ubuntu 20.04.

OpenSSL is an all-around cryptography library that offers an open-source application of the TLS protocol. It allows users to perform various SSL-related tasks, including CSR (Certificate Signing Request) private key generation, and SSL certificate installation.

The version of OpenSSL available on Ubuntu is a bit old (V1.1) and some applications will give errors when compiling if it requires a newer release. So we want to show you to install the latest release of OpenSSL on Ubuntu 20.04.

Next, use the following commands to build OpenSSL 3.0:

# make
# make test
# make install

Update links and caches by using the command below:

sudo ldconfig

Then, update your system-wide OpenSSL configuration:

sudo tee /etc/profile.d/<<EOF
export PATH=/usr/local/openssl/bin:\$PATH
export LD_LIBRARY_PATH=/usr/local/openssl/lib:\$LD_LIBRARY_PATH

Reload shell environment:

source /etc/profile.d/
