DESCRIPTION
These functions decode and encode PKCS#12 structures. For details about the semantics, examples, caveats, and bugs, see ASN1_item_d2i(3).

d2i_PKCS12() and i2d_PKCS12() decode and encode an ASN.1 PFX (personal information exchange) structure defined in RFC 7292 section 4. d2i_PKCS12_bio(), i2d_PKCS12_bio(), d2i_PKCS12_fp(), and i2d_PKCS12_fp() are similar except that they decode or encode using a BIO or FILE pointer.

d2i_PKCS12_MAC_DATA() and i2d_PKCS12_MAC_DATA() decode and encode an ASN.1 MacData structure defined in RFC 7292 section 4.

d2i_PKCS12_SAFEBAG() and i2d_PKCS12_SAFEBAG() decode and encode an ASN.1 SafeBag structure defined in RFC 7292 section 4.2.

d2i_PKCS12_BAGS() and i2d_PKCS12_BAGS() decode and encode the bagValue field of an ASN.1 SafeBag structure.

RETURN VALUES
d2i_PKCS12(), d2i_PKCS12_bio(), and d2i_PKCS12_fp() return a PKCS12 object or NULL if an error occurs.

d2i_PKCS12_MAC_DATA(), d2i_PKCS12_SAFEBAG(), and d2i_PKCS12_BAGS() return a PKCS12_MAC_DATA, PKCS12_SAFEBAG, or PKCS12_BAGS object, respectively, or NULL if an error occurs.

i2d_PKCS12(), i2d_PKCS12_MAC_DATA(), i2d_PKCS12_SAFEBAG(), and i2d_PKCS12_BAGS() return the number of bytes successfully encoded or a negative value if an error occurs.

i2d_PKCS12_bio() and i2d_PKCS12_fp() return 1 for success or 0 if an error occurs.
