SYNOPSIS

#include <libtasn1.h>

asn1_retCode asn1_der_decoding(ASN1_TYPE * element, const void * ider, int len, char * errorDescription);

ARGUMENTS

ASN1_TYPE * element pointer to an ASN1 structure.
const void * ider vector that contains the DER encoding.
int len number of bytes of *ider: ider[0]..ider[len-1].
char * errorDescription null-terminated string contains details when an error occurred.

DESCRIPTION

Fill the structure *ELEMENT with values of a DER encoding string. The structure must just be created with function asn1_create_element(). If an error occurs during the decoding procedure, the *ELEMENT is deleted and set equal to ASN1_TYPE_EMPTY.
