asn1_der_decoding - API function

#include <libtasn1.h>

int asn1_der_decoding(asn1_node * */element/, const void * ider, int ider_len, char * errorDescription);*

asn1_node * element

pointer to an ASN1 structure.

const void * ider

vector that contains the DER encoding.

int ider_len

number of bytes of * ider : ider [0].. ider [len-1].

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().

Note that the * element variable is provided as a pointer for historical reasons.

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).
