Hi,
In an application we are using the certificate authentication to validate the
user and am using X509 certificates for this authentication. To read these
certificates am using the open-ssl functions in my code.
My requirement is to get the value of the extension from the configuration file
for each CA (certificate authority). That's the reason am using the below
function to get the value of the extension and my code looks like as below.
============================
STACK_OF(GENERAL_NAME) *altnames;
int nid=0;
nid=OBJ_sn2nid(trimmedExtensionName);
altnames = (STACK_OF(GENERAL_NAME) *)X509_get_ext_d2i(cert, nid, NULL, NULL);
================================================
In some cases the function X509_get_ext_d2i function is executing
successfully and in some case it is failing and when it fails the total system
is crashing. We are unable to decide why it is failing sometimes. Please let me
know if anybody faced the same problems or anybody aware of this function.
Regards
Sunil.
