* In older `httplib`, SSL connections were not handled correctly and will have issues with proxy servers. Also, keep alive directives were not available back then, which is probably necessary to implement HTTP_C service correctly. * Another reason being `httplib` now requires OpenSSL 1.1+ API while LibreSSL 2.x provided OpenSSL 1.0 compatible API. * The bundled LibreSSL has been updated to 3.2.2 so it now provides OpenSSL 1.1 compatible API now. * Also the path hint has been added so that it will find the correct path to the CA certs on *nix systems. * An option is provided so that *nix system distributions/providers can use their own SSL implementations when compiling Yuzu/Citra to (hopefully) complies with their maintenance guidelines. * LURLParse is also removed since `httplib` can handle `scheme:host:port` string itself now.

/* Quote from RFC2818 section 3.1 "Server Identity"
|
|
|
|
If a subjectAltName extension of type dNSName is present, that MUST
|
|
be used as the identity. Otherwise, the (most specific) Common Name
|
|
field in the Subject field of the certificate MUST be used. Although
|
|
the use of the Common Name is existing practice, it is deprecated and
|
|
Certification Authorities are encouraged to use the dNSName instead.
|
|
|
|
Matching is performed using the matching rules specified by
|
|
[RFC2459]. If more than one identity of a given type is present in
|
|
the certificate (e.g., more than one dNSName name, a match in any one
|
|
of the set is considered acceptable.) Names may contain the wildcard
|
|
character * which is considered to match any single domain name
|
|
component or component fragment. E.g., *.a.com matches foo.a.com but
|
|
not bar.foo.a.com. f*.com matches foo.com but not bar.com.
|
|
|
|
In some cases, the URI is specified as an IP address rather than a
|
|
hostname. In this case, the iPAddress subjectAltName must be present
|
|
in the certificate and must exactly match the IP in the URI.
