.Sh DESCRIPTION
.Fn PKCS12_new
allocates and initializes an empty
.Vt PKCS12
object, representing an ASN.1
.Vt PFX
.Pq personal information exchange
structure defined in RFC 7292 section 4.
It can hold a pointer to a
.Vt PKCS7
object described in
.Xr PKCS7_new 3
and optionally an instance of
.Vt PKCS12_MAC_DATA
described below.
.Fn PKCS12_free
frees
.Fa pfx .

.Vt PKCS12_MAC_DATA
object, representing an ASN.1
.Vt MacData
structure defined in RFC 7292 section 4.
It is used inside
.Vt PKCS12
and can hold a pointer to an
.Vt X509_SIG
object described in
.Xr X509_SIG_new 3
together with a salt value and an iteration count.
.Fn PKCS12_MAC_DATA_free
frees
.Fa mac_data .
.Sh RETURN VALUES
.Fn PKCS12_new
and
.Fn PKCS12_MAC_DATA_new
return the new
.Vt PKCS12
or
.Vt PKCS12_MAC_DATA
object, respectively, or
.Dv NULL
if an error occurs.
