Hi list members,

I have a .p7f in hands, which seems to be a DER encoded PKCS7 structure in some way, I can use 'openssl pkcs' to transform it in a PEM form, I also can pull a bunch of certificates out of it. But I know, there is some encrypted pay load in this file, which I can not decipher. What I have tried with openssl's rsautl and smime does not seem to work for me.

May be someone of you can push me in the right direction, thanks!
Try the "openssl cms" command, or its older sibling "openssl smime" .

Enjoy

Jakob
