I'm not sure what you mean by "PKCS7 certificate". PKCS7 is (among other
things) a format for packaging certificates but not a certificate format
itself.

You can extract a certificate from a PKCS#12 file using PKCS12_parse() and
convert it to PKCS#7 format using the PKCS7 APIs (see crl2pkcs7 for an
example).
