If you are using RHEL on EC2, you can enable the optional channel by running:

$ yum -y install yum-utils
$ yum-config-manager --enable rhui-REGION-rhel-server-extras rhui-REGION-rhel-server-optional

After doing this, you can install Certbot by running:

$ sudo yum install certbot

sudo certbot certonly -d domain_name_here_com

sudo cat /etc/letsencrypt/domain_name_here_com/*.pem > ~/fullcert.pem

openssl pkcs12 -export -out domain_name_here_com.pkcs12 -in fullchain.pem
