PKCS12_init() creates an empty PKCS#12 structure. Any PKCS#7 authSafes added to this structure are
       enclosed first within a single PKCS#7 contentInfo of type mode. Currently the only supported type is
       NID_pkcs7_data.

       PKCS12_init_ex() creates an empty PKCS#12 structure and assigns the supplied ctx and propq to be used to
       select algorithm implementations for operations performed on the PKCS12 object.

PKCS12_init_ex() was added in OpenSSL 3.0.

       PKCS12_init, PKCS12_init_ex - Create a new empty PKCS#12 structure

PKCS12_init() and PKCS12_init_ex() return a valid PKCS12 structure or NULL if an error occurred.
