       These functions add a PKCS#12 Attribute to the Attribute Set of the bag.

       PKCS12_add1_attr_by_NID() adds an attribute of type nid with a value of ASN1 type type constructed using
       len bytes from bytes.

       PKCS12_add1_attr_by_txt() adds an attribute of type attrname with a value of ASN1 type type constructed
       using len bytes from bytes.

       PKCS12_add1_attr_by_NID, PKCS12_add1_attr_by_txt - Add an attribute to a PKCS#12 safeBag structure

       These functions do not check whether an existing attribute of the same type is present. There can be
       multiple attributes with the same type assigned to a safeBag.

       Both functions were added in OpenSSL 3.0.

       A return value of 1 indicates success, 0 indicates failure.
