       These functions create a new PKCS12_SAFEBAG and add it to the set of safeBags in 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 EVP_PKEY and adds this to the set of PKCS#12 safeBags. If key_nid is not -1 then the key is
       encrypted with the supplied algorithm, using pass as the passphrase and iter as the iteration count. If
       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 ctx and property
       query propq to be used to select algorithm implementations.

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

PKCS12_add_secret() and PKCS12_add_key_ex() were added in OpenSSL 3.0.

       PKCS12_add_cert, PKCS12_add_key, PKCS12_add_key_ex, PKCS12_add_secret - Add an object to a set of PKCS#12
       safeBags

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

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

       A valid PKCS12_SAFEBAG structure or NULL if an error occurred.
