#Step 2. Installing OpenSSL on Ubuntu 20.04.

#Now we download the source code OpenSSL from the official page:

cd /usr/local/src/
wget https://www.openssl.org/source/openssl-1.1.1k.tar.gz
sudo tar -xf openssl-1.1.1k.tar.gz
cd openssl-1.1.1k

#Then, we configure and compile OpenSSL:

sudo ./config --prefix=/usr/local/ssl --openssldir=/usr/local/ssl shared zlib
sudo make
sudo make test
sudo make install
