Hi Karl,
I believe it could be helpful to have a look at the 509_check_host() and do_x509_check() source code in crypto\x509v3\v3_utl.c. Also, if you want to parse the SAN just for certificate validation, it is now easier to use : https://www.openssl.org/docs/manmaster/crypto/X509_VERIFY_PARAM_set_flags.html Hope this helps, Regards, Michel.

It looks a bit arcane....
