Protect Your Websites with Let's Encrypt
by Carla Schroder
Back in the bad old days, setting up basic HTTPS with a certificate authority cost as much as several hundred dollars per year, and the process was difficult and error-prone to set up. Now we have Let’s Encrypt for free, and the whole thing takes just a few minutes.
Why encrypt your sites? Because unencrypted HTTP sessions are wide open to multiple abuses:
- Eavesdropping on your users
- Capturing user logins
- Injecting ads and “important” messages
- Injecting spyware
- Injecting SEO spam and links
- Injecting cryptocurrency miners
Internet service providers lead the code-injecting offenders. How to foil their nefarious desires? Your best defense is HTTPS. Let’s review how HTTPS works.
