=head1 DESCRIPTION

These functions create a new B<PKCS12_SAFEBAG> and add it to the set of safeBags
in I<pbags>.

PKCS12_add_cert() creates a PKCS#12 certBag containing the supplied
certificate and adds this to the set of PKCS#12 safeBags.

PKCS12_add_key() creates a PKCS#12 keyBag (unencrypted) or a pkcs8shroudedKeyBag
(encrypted) containing the supplied B<EVP_PKEY> and adds this to the set of PKCS#12
safeBags. If I<key_nid> is not -1 then the key is encrypted with the supplied
algorithm, using I<pass> as the passphrase and I<iter> as the iteration count. If
I<iter> is zero then a default value for iteration count of 2048 is used.

PKCS12_add_key_ex() is identical to PKCS12_add_key() but allows for a library
context I<ctx> and property query I<propq> to be used to select algorithm
implementations.

PKCS12_add_secret() creates a PKCS#12 secretBag with an OID corresponding to
the supplied I<nid_type> containing the supplied value as an ASN1 octet string.
This is then added to the set of PKCS#12 safeBags.

=head1 NOTES

If a certificate contains an I<alias> or a I<keyid> then this will be
used for the corresponding B<friendlyName> or B<localKeyID> in the
PKCS12 structure.

PKCS12_add_key() makes assumptions regarding the encoding of the given pass
phrase.
See L<passphrase-encoding(7)> for more information.

=head1 RETURN VALUES

A valid B<PKCS12_SAFEBAG> structure or NULL if an error occurred.
