SYNOPSIS¶

#include <libtasn1.h>

asn1_retCode asn1_der_decoding_element(ASN1_TYPE * structure, const char * elementName, const void * ider, int len, char * errorDescription);

ARGUMENTS¶

ASN1_TYPE * 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[0]..der[len-1]

char * errorDescription

null-terminated string contains details when an error occurred.

DESCRIPTION¶

Fill the element named ELEMENTNAME with values of a DER encoding string. The sructure must just be created with function string of the whole STRUCTURE. If an error occurs during the decoding procedure, the *STRUCTURE is deleted and set equal to ASN1_TYPE_EMPTY.
