How to Generate SSL Certificate Chain for Nginx

I’m using Comodo Certificate, you will get these files from their email:

  • Root CA Certificate – AddTrustExternalCARoot.crt
  • Intermediate CA Certificate – UTNAddTrustSGCCA.crt
  • Intermediate CA Certificate – ComodoUTNSGCCA.crt
  • Intermediate CA Certificate – EssentialSSLCA_2.crt
  • Your EssentialSSL Certificate – www_example_com.crt

Correct order:

  1. Your EssentialSSL Certificate – www_example_com.crt
  2. Intermediate CA Certificate – EssentialSSLCA_2.crt
  3. Intermediate CA Certificate – ComodoUTNSGCCA.crt
  4. Intermediate CA Certificate – UTNAddTrustSGCCA.crt
  5. Root CA Certificate – AddTrustExternalCARoot.crt

You can create a chained certificate required by Nginx:

cat www_example_com.crt EssentialSSLCA_2.crt ComodoUTNSGCCA.crt UTNAddTrustSGCCA.crt AddTrustExternalCARoot.crt > example.com.chained.crt

In fact, you can only need the first three certificates: most systems have their root CA.

cat www_example_com.crt EssentialSSLCA_2.crt ComodoUTNSGCCA.crt  > example.com.chained.crt

Update Mar 21, 2015:

Comodo updated their certificates filename, so the correct order now is:

  1. Your EssentialSSL Certificate – www_example_com.crt
  2. Intermediate CA Certificate – COMODORSADomainValidationSecureServerCA.crt
  3. Intermediate CA Certificate – COMODORSAAddTrustCA.crt
  4. Root CA Certificate – AddTrustExternalCARoot.crt
cat www_example_com.crt COMODORSADomainValidationSecureServerCA.crt COMODORSAAddTrustCA.crt > example.com.chained.crt
