Hello I am having the damnest time with OpenSSL and STunnel, and wanted to see if anyone could give me a swift kick in the right direction :). If you want to verify each entry in the file, you can use this script to show the chain of trust for a local certificate: ~ % ssl_chain.sh google.crtĠ: subject= /C=US/ST=California/L=Mountain View/O=Google Inc/CN=issuer= /C=US/O=Google Inc/CN=Google Internet Authority G2ġ: subject= /C=US/O=Google Inc/CN=Google Internet Authority G2 Verify the Signature on the new Certificate with the following command: openssl verify -CAfile ca.crt server.crt 6. The verify command you listed will fail if your system cannot validate the chain (example: you are missing an intermediate certificate or the root is not trusted), showing an error message like:Įrror 20 at 0 depth lookup:unable to get local issuer certificate Verify signature (SMIME) Verify that your file has been signed by using: openssl smime -verify -in ThirdPartyLegalNoticeReadme.p7s -signer keytool.

I am trying to set up a certificate chain for a lab server. Subject= /C=US/ST=Utah/L=SLC/O=My Organization/CN=my. The SSL certificate chain order consists of root certificates, intermediate certificates, and the end-user certificate. For local certificates you can see the subject and direct issuer using: openssl x509 -noout -subject -issuer -in test.crt
