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 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 ASN1_TYPE_EMPTY.

RETURNS

ASN1_SUCCESS if DER encoding OK, ASN1_ELEMENT_NOT_FOUND if ELEMENT is ASN1_TYPE_EMPTY or elementName == NULL, and ASN1_TAG_ERROR or ASN1_DER_ERROR if the der encoding doesn’t match the structure structure (*ELEMENT deleted).
