Per http://docs.aws.amazon.com/AmazonS3/latest/dev/BucketRestrictions.html: "We recommend that all bucket names comply with DNS naming conventions." Per http://docs.aws.amazon.com/AmazonS3/latest/dev/VirtualHosting.html: "When using virtual hosted-style buckets with SSL, the SSL wild card certificate only matches buckets that do not contain periods. To work around this, use HTTP or write your own certificate verification logic." Therefore, we need a custom validation routine that allows mybucket.example.com.s3.amazonaws.com to be considered a valid hostname for the *.s3.amazonaws.com wildcard cert, and for the region-specific *.s3-[region].amazonaws.com wildcard cert. We also forgive non-S3 wildcard certificates should the hostname match, to allow compatibility with other S3 API-compatible storage providers. z6checking SSL subjectAltName as forgiving wildcard certZsubjectAltNamer �https://ZDNSz*.s3z.amazonaws.comz.amazonaws.com.cnT�*)Zbucket�locationr!
