Does ELB Support Wildcard Certificates?

Yes.

Shared load balancers support the longest suffix match by default.

Dedicated load balancers using a SNI certificate support wildcard match by default. Only the subdomain names of the same level can be matched. You can change wildcard match to longest suffix match by changing the value of sni_match_algo. For details, see Elastic Load Balance API Reference.

**Table 1** Examples of wildcard-domain matching rules
Domain Name	Wildcard Match	Longest Suffix Match
*.example.com	Domain names, such as abc.example.com, sport.example.com, and good.example.com	Domain names, such as abc.example.com and mycalc.good.example.com
