I am a complete newbie to this list.

I wanted to search the archive but found no such page.


I have a requirement to convert all certs in a *.p12 file to a *.der file
for use in the curl command.

The first hop to a *.pem file has all the certs.

But the second hop only has one cert.  The I read the docs but found nothing
that looked even close.

Hop 1

openssl pkcs12 -chain -in trust.p12 -out ww_temp.pem  -password {redacted}


Hop 2

openssl x509 -outform der -in ww_temp.pem -out ww_temp.der


The Question) How do I get all the certs in the .der file?
