+=head1 NAME
+
+PKCS12_add_cert, PKCS12_add_key,
+PKCS12_add_secret - Add an object to a set of PKCS#12 safeBags
+
+=head1 SYNOPSIS
+
+ #include <openssl/pkcs12.h>
+
+ PKCS12_SAFEBAG *PKCS12_add_cert(STACK_OF(PKCS12_SAFEBAG) **pbags, X509 *cert);
+ PKCS12_SAFEBAG *PKCS12_add_key(STACK_OF(PKCS12_SAFEBAG) **pbags,
+                               EVP_PKEY *key, int key_usage, int iter,
+                               int key_nid, const char *pass);
+ PKCS12_SAFEBAG *PKCS12_add_secret(STACK_OF(PKCS12_SAFEBAG) **pbags,
+                                  int nid_type, const unsigned char *value, int len);
+
+=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_secret() creates a PKCS#12 secretBag with an OID corresponding to
+the supplied B<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 B<alias> or a B<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.
+
+PKCS12_add_secret() was added in OpenSSL 3.0.
+
+=head1 RETURN VALUES
+
+A valid B<PKCS12_SAFEBAG> structure or NULL if an error occurred.
