Answer 1

-print_certs is the option you want to use to list all of the certificates in the p7b file, you may need to specify the format of the p7b file you are reading.

You can then redirect the output to a new file to build the concatenated list of certificates.

Open the file in a text editor, you will either see Base64 (PEM) or binary data (DER).

openssl pkcs7 -inform DER -outform PEM -in certificate.p7b -print_certs > certificate_bundle.cer
