Run the commands below option Ubuntu default man page Compiling OpenSSL for Linux on Ubuntu 20.04 Start by making sure everything is up to date: apt-get update Now, let’s install some dependencies needed to build OpenSSL for Linux. Edit the file /etc/nfig adding the following line before the first MANPATH_MAP: For Ubuntu, this means making sure gcc is installed, as well as the dependencies for OpenSSL itself, namely checkinstall and zlib. To ensure that Ubuntu use this version of OpenSSL instead of the previous version you must update the paths for man pages and binaries.

You’ll need to reference the version you installed. Breaking down the command: openssl the command for executing OpenSSL. openssl pkcs7 -printcerts -in certificate.p7b -out certificate.crt. Provided by: openssl1.1.
Once converted to PEM, follow the above steps to create a PFX file from a PEM file. This particularly affects the use of encryption keys in OpenSSH, OpenVPN and SSL certificates. openssl req -new -newkey rsa:2048 -nodes -keyout yourdomain.key -out yourdomain. As a result of this weakness, certain encryption keys are much more common than they should be, such that an attacker could guess the key through a brute-force attack given minimal knowledge of the system. Then paste the following OpenSSL command modifying yourdomain to reflect the domain you will eventually add to the certificate.
Ubuntu default OpenSSL version is installed in the /usr/lib/ssl and it’s where apps that need to use SSL look by default. P7B files cannot be used to directly create a PFX file. Open Terminal or a command prompt and login to your server via SSH.
