asn1_der_decoding_element - API function
#include <libtasn1.h> int asn1_der_decoding_element(asn1_node * structure, const char * elementName, const void * ider, int len, char * errorDescription);
asn1_node * structure pointer to an ASN1 structure const char * elementName name of the element to fill const void * ider vector that contains the DER encoding of the whole structure. int len number of bytes of *der: der..der[len-1] char * errorDescription null-terminated string contains details when an error occurred.
Fill the element named ELEMENTNAME with values of a DER encoding string. The structure must just be created with function asn1_create_element(). The DER vector must contain the encoding string of the whole STRUCTURE . If an error occurs during the decoding procedure, the * STRUCTURE is deleted and set equal to NULL. This function is deprecated and may just be an alias to asn1_der_decoding in future versions. Use asn1_der_decoding() instead.
ASN1_SUCCESS if DER encoding OK, ASN1_ELEMENT_NOT_FOUND if ELEMENT is NULL or elementName == NULL, and ASN1_TAG_ERROR or ASN1_DER_ERROR if the der encoding doesn't match the structure structure (*ELEMENT deleted).
