I need a little fix on openssl, to manage the "SigningCertificateV2" attribute (OID 1.2.840.[login to view URL]; <[login to view URL]>), when signing and when verifiying a signed file.
SIGNING A FILE
**openssl smime -sign -md sha256 -in [login to view URL] -text -inkey [login to view URL] -signer [login to view URL] -outform DER -nodetach *+ an option of your choice* > [login to view URL]**
The output signed file *[login to view URL]* should include the "SigningCertificateV2" attribute.
VERIFYING A SIGNED FILE
**openssl pkcs7 -in test\[login to view URL] -inform DER -print\_certs *+ an option of your choice***
It should verify the presence of the "SigningCertificateV2" attribute too.
