The above command prints the complete certificate chain of google.com to stdout. Extracting the CA Certificate using OpenSSL. The Delphix engine requires certificates to be in the X.509 standard, and JKS or PKCS#12 file formats are supported. pkcs12 -in c:\work\cert.pfx -nodes -nokeys -out c:\work\chain.pem enter PFX password, chain.pem will be created *NOTE* this file contains the certificate itself as well as any other certificates needed back the root CA. Note. This is the format that is generally appended to digital signatures. The other file that stands out is fullchain.pem, the difference between chain.pem and fullchain.pem is that chain.pem only contains the intermediate certificate.
