- pedrocx486 6y agoDoesn't the title here literally say that it works with subdomains? Or I'm misunderstanding? (Not my field of work.)
- cpach 6y agoYes it does, due to the way that it’s structured. AFAICT, the wildcard symbol (asterisk) will not match across the separator (i.e. the period). So ¤.¤ will only match example.com or contoso.com etc, not blog.example.com or sales.contoso.com. If you look at the cert, it has lots of line that looks like this: DNS:¤.¤.¤.¤.¤.¤.¤.¤.¤.¤, DNS:¤.¤.¤.¤.¤.¤.¤.¤.¤.¤.¤, In that way it will match all possible levels of subdomains. (Asterisk substituted for ¤ in order to not trip up the formatting here on HN.)
- cpach 6y agoIf anyone finds 'x3n0ph3n3’s comment to look weird, it’s because HN ate the asterisks in there.
