I'm not sure what to do next. *If* an issuing cert has KeyUsage extension it must include certSign, but if the extension is absent (and all extensions are absent in v1) it is allowed for backward compatibility. I do this in test almost all the time because it's quicker to set up. How are you sure of your other statements above? As I read the code, verify 19 occurs only if the peer *does* send the root and it is *not* found in the local truststore. Is your truststore in OpenSSL's default format (CAfile and/or CApath) or can it be converted to that? If so, try commandline s_client which will show you the cert chain (and callback steps). (Even without any truststore it will show you the chain.) Are you sure you have the *correct* Verisign root? There are about a dozen published Verisign roots many of which have very similar -- but not identical -- names. They are not interchangeable, although in at least one case I looked at there is a "bridge" cert to (optionally and alternatively) chain a newer root to an older. ______________________________________________________________________ OpenSSL Project http://www.openssl.org User Support Mailing List openssl-users@openssl.org Automated List Manager majord...@openssl.org
