a further note on the regex.. /[Cc][Nn]=(?!([\-\w\*]+\.)+[\-\w]+)/
regex aficionados will note that there are subtle issues with the regex -- e.g. "([\-\w\*]+\.)+[\-\w]+)" -- the latter component doesn't /precisely/ describe DNS LDH domain name syntax. for instance, \w matches underscore, and thus the regex matches labels with underscore appearing anywhere in them, but (current) DNS LDH domain name syntax allows for underscore in only the first char position of a label. The regex also doesn't check for other first-char-of-label restrictions, and also matches wildcards anywhere in labels (which is a subtlety we've been debating).
However, I feel that for my present back-of-the-envelope quick looksee in the subject name data, that thar regex above is Good Enough.
Of course if others want to be more precise, go for it. =JeffH _______________________________________________ certid mailing list [email protected] https://www.ietf.org/mailman/listinfo/certid
