// According to the Baseline Requirements version 1.3.3 section 7.1.4.2.2.a,
|
||
// the requirements of the subject common name field are as follows:
|
||
// "If present, this field MUST contain a single IP address or Fully‐Qualified
|
||
// Domain Name that is one of the values contained in the Certificate’s
|
||
// subjectAltName extension". Consequently, since any name information present
|
||
// in the common name must be present in the subject alternative name extension,
|
||
// when performing name matching, it should not be necessary to fall back to the
|
||
// common name. Because this consequence has not commonly been enforced, this
|
||
// implementation provides a mechanism to start enforcing it gradually while
|
||
// maintaining some backwards compatibility. If configured with the mode
|
||
// "EnforceAfter23August2016", name matching will only fall back to using the
|
||
// subject common name for certificates where the notBefore field is before 23
|
||
// August 2016. Similarly, the mode "EnforceAfter23August2015" is also
|
||
// available. This is to provide a balance between allowing preexisting
|
||
// long-lived certificates and detecting newly-issued problematic certificates.
|
||
// Note that this implementation does not actually directly enforce that if the
|
||
// subject common name is present, its value corresponds to a dNSName or
|
||
// iPAddress entry in the subject alternative name extension.
