SSL Basics — Page 4

50 guides covering the foundations: what SSL/TLS is, how the handshake works, the cryptography underneath, and every certificate type and field you'll run into.

HTTP/2 and HTTPS: Why They're Linked

No major browser will negotiate HTTP/2 without TLS, even though the spec technically allows it.

Does SSL Affect Website Speed?

Yes, measurably — and the number is much smaller than most people assume, especially since TLS 1.3.

Does HTTPS Affect SEO Rankings?

Google confirmed it as a ranking signal in 2014 — the more interesting question is how much it still moves the needle.

Free vs Paid SSL Certificates: What's the Real Difference?

The encryption is identical. What you're actually paying for is validation depth, warranty, and support.

What Is Let's Encrypt and How Does It Work?

A nonprofit CA that made HTTPS free and automated — and quietly became the most-used certificate authority on the internet.

What Is ACME Protocol?

The automation standard that made Let's Encrypt's whole model possible — and now used well beyond it.

Understanding Certificate Key Lengths (RSA vs ECC)

A 256-bit ECC key isn't weaker than a 2048-bit RSA key — different algorithms, different math, different numbers.

What Is SSL Stripping?

An attack that doesn't break your encryption — it just makes sure the visitor never gets to use it.

Common Myths About SSL Certificates

A few beliefs that were once roughly true, and have since aged badly.

Do I Need SSL If My Site Doesn't Take Payments?

Short answer: yes. Here's the actual reasoning, not just the browser warning.
