I have a test certificate chain that I generated and it fails the openssl verify command:

openssl verify -CAfile ca_cert.pem -untrusted intermediate_cert.pem server_cert.pem

The output I get from the command is :

C = US, ST = CA, O = service, CN = service Test Cert
error 20 at 0 depth lookup: unable to get local issuer certificate

To me, this implies that openssl can verify the immediate cert, but not the server cert. Included below is the ca certificate, intermediate certificate and server certificate. Can anyone spot what the problem is?

The ca cert:

It seems these are test certificates, thus issued from a test CA. If they don't chain to a trusted CA you will get the above error. You may use -CAfile ca.pem to point to the CA so the intermediate is trusted, and then per the intermediate signatuere, the leaf certificate is as well

  • I think there is something wrong with the intermediate to leaf cert, but I did add the ca certificate to give a complete picture of the problem. – CryptoBipto Sep 21 '20 at 16:17

To me, this implies that openssl can verify the immediate cert, but not the server cert.

That's right. What you are missing is that openssl verify [options] file1 file2 ... validates (the one/first cert in) each file1, file2, etc. independently. What is happening is:

  1. OpenSSL tries to validate intermediate_cert.pem against the root ca_cert.pem. This succeeds.

  2. OpenSSL tries to validate server_cert.pem against the root ca_cert.pem. It completely ignores the intermediate_cert file used in step 1. Since server_cert was not issued directly under ca_cert and the intermediate is not available, validation fails.

What you want to do is openssl verify -CAfile ca_cert -untrusted imed_cert server_cert. This validates servercert using imed as a chain cert against the given root. Validating a chain includes verifying all non-root (technically, non-anchor) certs in the chain, so this verifies BOTH server_cert and imed_cert in one operation, giving an error if either (or more generally any) of them has a problem.

Dupes:
Why is OpenSSL verify output depending on source of cert files?

I thought there were more; I certainly have answered this question more times than those, but maybe they're deleted or unfindable or something.

  • Thanks for the advice, I've added the untrusted option and it still didn't work. I'm fairly certain that the verify command is working as it is supposed to, and openssl is correctly asserting that the certs don't match up in some way. But I don't have enough information to say why the last link is problematic. – CryptoBipto Sep 22 '20 at 18:54
  • Your Q now claims that verify ... -untrusted imed server outputs imed: OK which is impossible; that file is no longer an operand (only an option). I don't have your certs, but I created a test set with the same attributes as nearly as possible (except serials, dates, and actual keys, and of course hashes and signatures) and they verify as expected. Without actual certs, I am going to consider this unreproducable. – dave_thompson_085 Sep 24 '20 at 8:31
  • Thanks for looking into this. At least I know it's not something obvious! – CryptoBipto Sep 25 '20 at 19:34
