func ToX500Name

func ToX500Name(asn1Name []byte) (string, error)

Convert a name from an X509 certificate into a string

We cannot use the Go method pkix.Name.ToString() function as the whole name decoding logic in Go is full of assumptions which are not correct. Go takes the RDNSequence and re-arranges and re-encodes the entries in a way that they no longer correspond to the original sequence. Thus we simply take the raw value, and encode it ourselves as string.
