# TODO: `rustls` (really, `webpki`) doesn't currently use the CN in the subject
|
|
# to check if a certificate is valid for a server name sent via SNI. It's not
|
|
# clear if this is intended, since certificates _should_ have a `subjectAltName`
|
|
# with a DNS name, or if it simply hasn't been implemented yet. See

# https://bugzilla.mozilla.org/show_bug.cgi?id=552346 for a bit more info.
