Ssl – “Issued certificate not yet valid.” with wget

I studied a week on this, finaly with the help I got from this page.

The command I used to connect is:

wget --ca-cert=/etc/ssl/certs/winhostname.pem --certificate=/etc/ssl/private/linuxhost.pem \
     --private-key=/etc/ssl/private/linuxhost.key https://winhostname.home.net:8443/winhosturl.asmx

Be sure to include all the intermediate certificates and see that they are up to date. If test.crt is in fact a file containing only /C=SE/O=AddTrust AB/OU=AddTrust External TTP Network/CN=AddTrust External CA Root, this is the correct approach. You can include the root as well, and most clients will accept such chains, but a few will choke.

In general it's best practice to include all the certificates from yours to the last one before the root, in case a client doesn't have the last intermediate.

It's also possible that test.crt contains things other than the correct chain. OpenSSL doesn't do partial chain validation by default (in older versions, it doesn't do it at all). When operating in this mode it doesn't care what is in /etc/ssl/certs.

Alternatively, you may be presenting an expired intermediary certificate. CAs often recertify their intermediates with the same key; if they do that, just download the updated intermediate CA certificate and replace the expired one in your chain.

Finally, with openssl s_client, you need to specify what it is validating against. For example, use the option -CApath /etc/ssl/certs or -CAfile your_ca.crt. For the first option use your system's trust store, and for the second option specify the root CA certificate.
