3.1 - 7

PKCS#7 does not include the private key, it is commonly used for certificate dissemination (e.g. as the response to a PKCS#10 certificate request, as a means to distribute S/MIME certs used to encrypt messages, or to validate signed messages etc).

It is important to remember that it is only for certificates which are by definition public items.

You cannot convert from PKCS#7 to PKCS#12 without additional data (the private key part) because PKCS#7 doesn't have all of the data.
