How to validate PFX with public-key privacy/integrity mode

Question

I have a piece of embedded software generating P12/PFX formatted output data.
The PFX is not password protected, that means instead of using a password-derived encryption/mac key the data is encrypted with a public key and signed with my private key.
In RFC7292 section 3.1 this is called public-key privacy and integrity modes.

My question is, how can I validate the PFX I receive, e.g. using openssl? (I'm not restricted to use openssl, by the way I google'd around but could not find a way...)

I tried

openssl pkcs12 -info -in test.pfx

but openssl requests a password, which is not applicable here. Did I miss any option to not being asked for a password?

Answer 1

openssl pkcs12 -info -in test.pfx -passin pass: -passout pass: 

Alternatively, you can just use

openssl pkcs12 -info -in test.pfx

and when it asks for Import Password or PEM Pass Phrase (and you didn't use any while generating the pfx file), just press Enter.
