asn1_der_coding - API function

       asn1_node_const element
                   pointer to an ASN1 element

       const char * name
                   the name of the structure you want to encode (it must be inside *POINTER).

       void * ider vector that will contain the DER encoding. DER must be a  pointer  to  memory  cells  already
                   allocated.

       int * len   number  of  bytes  of  *  ider  :  ider [0].. ider [len-1], Initially holds the sizeof of der
                   vector.

       char * ErrorDescription
                   return the error description or an empty string if success.

       Creates the DER encoding for the NAME structure (inside *POINTER structure).

       asn1_der_coding - API function

ASN1_SUCCESS  if  DER  encoding  OK,  ASN1_ELEMENT_NOT_FOUND  if   name   is   not   a   valid   element,
       ASN1_VALUE_NOT_FOUND if there is an element without a value, ASN1_MEM_ERROR if the  ider vector isn't big
       enough and in this case  len will contain the length needed.
