If you run openssl x509 -in /tmp/DigiCertSHA2HighAssuranceServerCA.pem -noout -issuer_hash you get 244b5494, which you can look for in the system root CA store at /etc/ssl/certs/244b5494.0 (just append. That "CA Issuers" URI points to the intermediate cert (in DER format, so you need to use openssl x509 -inform der -in DigiCertSHA2HighAssuranceServerCA.crt -out DigiCertSHA2HighAssuranceServerCA.pem to convert it for further use by OpenSSL). As an example, openssl x509 -in se.crt -noout -text contains: Authority Information Access: That's just how X.509 works.ĭepending on the certificate, it may contain a URI to get the intermediate from. If you don't have the intermediate certificate(s), you can't perform the verify. The depth=2 result came from the system trusted CA store. The -untrusted option is used to give the intermediate certificate(s) se.crt is the certificate to verify. Now, if I save those two certificates to files, I can use openssl verify: $ openssl verify -show_chain -untrusted dc-sha2.crt se.crtĭepth=0: C = US, ST = NY, L = New York, O = "Stack Exchange, Inc.", CN = *. (untrusted)ĭepth=1: C = US, O = DigiCert Inc, OU = CN = DigiCert SHA2 High Assurance Server CA (untrusted)ĭepth=2: C = US, O = DigiCert Inc, OU = CN = DigiCert High Assurance EV Root CA That will show the certificate chain and all the certificates the server presented. ![]() From a web site, you can do: openssl s_client -showcerts -verify 5 -connect :443 < /dev/null
