asn1_der_decoding2 - API function

       asn1_node * element
                   pointer to an ASN1 structure.

       const void * ider
                   vector that contains the DER encoding.

       int * max_ider_len
                   pointer to an integer giving the information about the maximal number of bytes occupied by  *
                   ider . The real size of the DER encoding is returned through this pointer.

       unsigned int flags
                   flags controlling the behaviour of the function.

       char * errorDescription
                   null-terminated string contains details when an error occurred.

       Fill  the  structure  *  element with values of a DER encoding string. The structure must just be created
       with function asn1_create_element().

       If ASN1_DECODE_FLAG_ALLOW_PADDING flag is set then the function will ignore padding after the decoded DER
       data. Upon a successful return the value of * max_ider_len will be set to the number of bytes decoded.

       If ASN1_DECODE_FLAG_STRICT_DER flag is set then the function will not decode any BER-encoded elements.

ASN1_SUCCESS if DER encoding OK, ASN1_ELEMENT_NOT_FOUND  if   ELEMENT  is  NULL,  and  ASN1_TAG_ERROR  or
       ASN1_DER_ERROR if the der encoding doesn't match the structure name (* ELEMENT deleted).
