DESCRIPTION

       X509_NAME_ENTRY_get_object() retrieves the field name of ne in and ASN1_OBJECT structure.

       X509_NAME_ENTRY_get_data() retrieves the field value of ne in and ASN1_STRING structure.

       X509_NAME_ENTRY_set_object() sets the field name of ne to obj.

       X509_NAME_ENTRY_set_data() sets the field value of ne to string type type and value determined by bytes
       and len.

       X509_NAME_ENTRY_create_by_txt(), X509_NAME_ENTRY_create_by_NID() and X509_NAME_ENTRY_create_by_OBJ()
       create and return an X509_NAME_ENTRY structure.

NOTES

       X509_NAME_ENTRY_get_object() and X509_NAME_ENTRY_get_data() can be used to examine an X509_NAME_ENTRY
       function as returned by X509_NAME_get_entry() for example.

       X509_NAME_ENTRY_create_by_txt(), X509_NAME_ENTRY_create_by_OBJ(), X509_NAME_ENTRY_create_by_NID() and
       X509_NAME_ENTRY_set_data() are seldom used in practice because X509_NAME_ENTRY structures are almost
       always part of X509_NAME structures and the corresponding X509_NAME functions are typically used to
       create and add new entries in a single operation.

       The arguments of these functions support similar options to the similarly named ones of the corresponding
       X509_NAME functions such as X509_NAME_add_entry_by_txt(). So for example type can be set to MBSTRING_ASC
       but in the case of X509_set_data() the field name must be set first so the relevant field information can
       be looked up internally.

RETURN VALUES

       X509_NAME_ENTRY_get_object() returns a valid ASN1_OBJECT structure if it is set or NULL if an error
       occurred.

       X509_NAME_ENTRY_get_data() returns a valid ASN1_STRING structure if it is set or NULL if an error
       occurred.

       X509_NAME_ENTRY_set_object() and X509_NAME_ENTRY_set_data() return 1 on success or 0 on error.

       X509_NAME_ENTRY_create_by_txt(), X509_NAME_ENTRY_create_by_NID() and X509_NAME_ENTRY_create_by_OBJ()
       return a valid X509_NAME_ENTRY on success or NULL if an error occurred.
