Hi Peter, > Read apps/x509.c how it parses the different ways to format a subject > and issuer.
I've looked at that file but my understanding is still limited. There's virtually no comments so it's hard to untangle what it is doing. I noticed a function X509_subject_name_hash(). Will that give a unique reference to a certificate? It seems to ;-) Cheers, Mark ______________________________________________________________________ OpenSSL Project http://www.openssl.org User Support Mailing List openssl-users@openssl.org Automated List Manager [EMAIL PROTECTED]
