DESCRIPTION

     An X.501 RelativeDistinguishedName is a set of field type and value
     pairs.  It is the building block for constructing X.501 Name objects.
     This implementation only supports sets with one element, so an
     X509_NAME_ENTRY object contains only one field type and one value.

     X509_NAME_ENTRY_new() allocates and initializes an empty X509_NAME_ENTRY
     object, representing an ASN.1 RelativeDistinguishedName structure defined
     in RFC 5280 section 4.1.2.4.

     X509_NAME_ENTRY_free() frees ne and the type and value contained in it.

     X509_NAME_ENTRY_get_object() retrieves the field type of ne in an
     ASN1_OBJECT structure.  X509_NAME_ENTRY_get_data() retrieves the field
     value of ne in an ASN1_STRING structure.  These two functions can be used
     to examine an X509_NAME_ENTRY object as returned by
     X509_NAME_get_entry(3).

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

     X509_NAME_ENTRY_set_data() sets the field value of ne to string type type
     and the 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.

     Except for X509_NAME_ENTRY_get_object() and X509_NAME_ENTRY_get_data(),
     these functions are rarely used because X509_NAME_ENTRY structures are
     almost always part of X509_NAME structures and the functions described in
     X509_NAME_add_entry_by_txt(3) 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 described in X509_NAME_add_entry_by_txt(3).  So for example
     type can be set to MBSTRING_ASC, but in the case of
     X509_NAME_ENTRY_set_data() the field type must be set first so the rele-
     vant field information can be looked up internally.


RETURN VALUES

     X509_NAME_ENTRY_new(), 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 structure on success or NULL if an error
     occurred.

     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.

HISTORY

     X509_NAME_ENTRY_new() and X509_NAME_ENTRY_free() first appeared in SSLeay
     0.5.1.  X509_NAME_ENTRY_get_object(), X509_NAME_ENTRY_get_data(),
     X509_NAME_ENTRY_set_object(), X509_NAME_ENTRY_set_data(),
     X509_NAME_ENTRY_create_by_NID(), and X509_NAME_ENTRY_create_by_OBJ()
     first appeared in SSLeay 0.8.0.  These functions have been available
     since OpenBSD 2.4.

     X509_NAME_ENTRY_create_by_txt() first appeared in OpenSSL 0.9.5 and has
     been available since OpenBSD 2.7.
