SSLGuides.com is a reference site for people who have to actually deal with SSL/TLS certificates — installing one for the first time, migrating an existing site to HTTPS, or figuring out why a browser is suddenly throwing a warning it wasn't yesterday.
Most certificate documentation assumes you already know the vocabulary. We try to do the opposite: explain what's actually happening, in order, without skipping the step that seems "obvious" to someone who's done it fifty times.
Some pages, particularly in the Buy a Certificate category, include affiliate links to certificate vendors. We only link to products we'd genuinely recommend, and it never affects how a guide is written. Full detail is in our disclaimer.
