NAME

asn1_der_decoding_startEnd - Find the start and end point of an element in a DER encoding string.  

SYNOPSIS

#include <libtasn1.h>

asn1_retCode asn1_der_decoding_startEnd(ASN1_TYPE element, const void * ider, int len, const char * name_element, int * start, int * end);  

ARGUMENTS

ASN1_TYPE element
pointer to an ASN1 element
const void * ider
vector that contains the DER encoding.
int len
number of bytes of *ider: ider[0]..ider[len-1]
const char * name_element
an element of NAME structure.
int * start
the position of the first byte of NAME_ELEMENT decoding (ider[*start])
int * end
the position of the last byte of NAME_ELEMENT decoding (ider[*end])
 

DESCRIPTION

Find the start and end point of an element in a DER encoding string. I mean that if you have a der encoding and you have already used the function "asn1_der_decoding" to fill a structure, it may happen that you want to find the piece of string concerning an element of the structure.  

EXAMPLE

the sequence "tbsCertificate" inside an X509 certificate.  

RETURNS

 

ASN1_SUCCESS

DER encoding OK.  

ASN1_ELEMENT_NOT_FOUND

ELEMENT is ASN1_TYPE EMPTY or NAME_ELEMENT is not a valid element.

ASN1_TAG_ERROR,ASN1_DER_ERROR: the der encoding doesn't match the structure ELEMENT.
