asn1_der_decoding_startEnd - API function
int asn1_der_decoding_startEnd(asn1_node element, const void *
ider, int ider_len, const char *
name_element, int * start, int *
- asn1_node element
- pointer to an ASN1 element
- const void * ider
- vector that contains the DER encoding.
- int ider_len
- number of bytes of * ider : ider ..
- const char * name_element
- an element of NAME structure.
- int * start
- the position of the first byte of NAME_ELEMENT decoding (
- int * end
- the position of the last byte of NAME_ELEMENT decoding (
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
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
Note that since libtasn1 3.7 the ider
be omitted, if the element is already decoded using
if DER encoding OK, ASN1_ELEMENT_NOT_FOUND
EMPTY or name_element
is not a valid element,
if the der encoding doesn't
match the structure ELEMENT.
