asn1_der_decoding_startEnd(3) libtasn1 asn1_der_decoding_startEnd(3) 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. COPYRIGHT

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. COPYRIGHT
