Calling
x509cert:extensions()on a certificate containing iPAddress SANs will return those IP addresses as raw bytes.Additionally, if combined with
x509cert:setencode("utf8"), theASN1_STRING_to_UTF8()call will fail and nothing will be pushed.The first first 3 commits fixes issues by returning nil instead of something invalid. The last commit uses
inet_ntop()to convert IP addresses to the common string form.
