asn1_der_decoding - API function
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.
RETURNS
ASN1_SUCCESS if DER encoding OK, ASN1_ELEMENT_NOT_FOUND if ELEMENT is ASN1_TYPE_EMPTY, and ASN1_TAG_ERROR or ASN1_DER_ERROR if the der
encoding doesn't match the structure name (*ELEMENT deleted).

asn1_der_decoding_startEnd - API function
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.
One example is the sequence "tbsCertificate" inside an X509 certificate.
RETURNS
ASN1_SUCCESS if DER encoding OK, ASN1_ELEMENT_NOT_FOUND if ELEMENT is ASN1_TYPE EMPTY or name_element is not a valid element,
ASN1_TAG_ERROR or ASN1_DER_ERROR if the der encoding doesn't match the structure ELEMENT.
