.Sh DESCRIPTION
These functions decode and encode PKCS#12 structures.
For details about the semantics, examples, caveats, and bugs, see
.Xr ASN1_item_d2i 3 .
.Pp
.Fn d2i_PKCS12
and
.Fn i2d_PKCS12
decode and encode an ASN.1
.Vt PFX
.Pq personal information exchange
structure defined in RFC 7292 section 4.
.Fn d2i_PKCS12_bio ,
.Fn i2d_PKCS12_bio ,
.Fn d2i_PKCS12_fp ,
and
.Fn i2d_PKCS12_fp
are similar except that they decode or encode using a
.Vt BIO
or
.Vt FILE
pointer.
.Pp
.Fn d2i_PKCS12_MAC_DATA
and
.Fn i2d_PKCS12_MAC_DATA
decode and encode an ASN.1
.Vt MacData
structure defined in RFC 7292 section 4.
.Pp
.Fn d2i_PKCS12_SAFEBAG
and
.Fn i2d_PKCS12_SAFEBAG
decode and encode an ASN.1
.Vt SafeBag
structure defined in RFC 7292 section 4.2.
.Pp
.Fn d2i_PKCS12_BAGS
and
.Fn i2d_PKCS12_BAGS
decode and encode the bagValue field of an ASN.1
.Vt SafeBag
structure.
.Sh RETURN VALUES
.Fn d2i_PKCS12 ,
.Fn d2i_PKCS12_bio ,
and
.Fn d2i_PKCS12_fp
return a
.Vt PKCS12
object or
.Dv NULL
if an error occurs.
.Pp
.Fn d2i_PKCS12_MAC_DATA ,
.Fn d2i_PKCS12_SAFEBAG ,
and
.Fn d2i_PKCS12_BAGS
return a
.Vt PKCS12_MAC_DATA ,
.Vt PKCS12_SAFEBAG ,
or
.Vt PKCS12_BAGS
object, respectively, or
.Dv NULL
if an error occurs.
.Pp
.Fn i2d_PKCS12 ,
.Fn i2d_PKCS12_MAC_DATA ,
.Fn i2d_PKCS12_SAFEBAG ,
and
.Fn i2d_PKCS12_BAGS
return the number of bytes successfully encoded or a negative value
if an error occurs.
.Pp
.Fn i2d_PKCS12_bio
and
.Fn i2d_PKCS12_fp
return 1 for success or 0 if an error occurs.
