Industry pundits advocate use of encryption. Unfortunately the certificates broke the budget of most web sites. I attempted to maintain SSL certificates, however they actually cost more than the revenue I received from advertising.
It also takes a huge amount of time to update certificates.
I used the instructions on Digital Ocean to load a program called certbot. I then installed certificates on irivers.com, communitycolor.com, pcut.net and gjct.com. I also installed an SSL certificate on my blog site.
