=head1 DESCRIPTION

PKCS12_SAFEBAG_get0_attr() gets the attribute value corresponding to the B<attr_nid>.

PKCS12_SAFEBAG_get0_type() gets the B<safeBag> type as an OID, whereas
PKCS12_SAFEBAG_get_nid() gets the B<safeBag> type as an NID, which could be
B<NID_certBag>, B<NID_crlBag>, B<NID_keyBag>, B<NID_secretBag>, B<NID_safeContentsBag>
or B<NID_pkcs8ShroudedKeyBag>.

PKCS12_SAFEBAG_get_bag_nid() gets the type of the object contained within the
B<PKCS12_SAFEBAG>. This corresponds to the bag type for most bags, but can be
arbitrary for B<secretBag>s. PKCS12_SAFEBAG_get0_bag_type() gets this type as an OID.

PKCS12_SAFEBAG_get0_bag_obj() retrieves the object contained within the safeBag.

PKCS12_SAFEBAG_get1_cert_ex() and PKCS12_SAFEBAG_get1_crl_ex() return new B<X509> or
B<X509_CRL> objects from the item in the safeBag. I<libctx> and I<propq> are used when
fetching algorithms, and may optionally be set to NULL.

PKCS12_SAFEBAG_get1_cert() and PKCS12_SAFEBAG_get1_crl() are the same as
PKCS12_SAFEBAG_get1_cert_ex() and PKCS12_SAFEBAG_get1_crl_ex() and set the I<libctx> and
I<prop> to NULL. This will use the default library context.

PKCS12_SAFEBAG_get0_p8inf() and PKCS12_SAFEBAG_get0_pkcs8() return the PKCS8 object
from a PKCS8shroudedKeyBag or a keyBag.

PKCS12_SAFEBAG_get0_safes() retrieves the set of B<safeBags> contained within a
safeContentsBag.

=head1 RETURN VALUES

PKCS12_SAFEBAG_get_nid() and PKCS12_SAFEBAG_get_bag_nid() return the NID of the safeBag
or bag object, or -1 if there is no corresponding NID.
Other functions return a valid object of the specified type or NULL if an error occurred.
