Struct webpki::subject_name::dns_name::WildcardDnsNameRef

source ·
pub struct WildcardDnsNameRef<'a>(&'a [u8]);
Expand description

A reference to a DNS Name presented by a server that may include a wildcard.

A WildcardDnsNameRef is guaranteed to be syntactically valid. The validity rules are specified in RFC 5280 Section 7.2, except that underscores are also allowed.

Additionally, while [RFC6125 Section 4.1] says that a wildcard label may be of the form <x>*<y>.<DNSID>, where <x> and/or <y> may be empty, we follow a stricter policy common to most validation libraries (e.g. NSS) and only accept wildcard labels that are exactly *.
