If the *.pkcs7 file is in binary format this would be a starting point: openssl smime -verify -in foo.pkcs7 -content foo.pdf -inform DER -binary that will probably complain about being unable to find the issuer certificate. For testing purposes you can include the -noverify option which will tell you it has otherwise checked the signature. If that works you need to trust the appropriate root CA(s) and pass them to it using the -CAfile or -CApath options. Steve. -- Dr Stephen N. Henson.
