My first attempt at using OpenSSL. (BTW I haven't found anything much in the
way of documentation - is there any that I might have missed?)
The first thing I'm trying to do is call d2i_PKCS12_fp, so this call is the
very first line of OpenSSL I've written.
It fails. In particular it eventually calls down to _setmode in the C
runtime library which fails at this line:
_VALIDATE_RETURN((_osfile(fh) & FOPEN), EBADF, -1);
I've found various things about crashes in d2i_PKCS12_fp, so I'm including
applink.c and calling CRYPTO_malloc_init, and I've found the sample code for
reading a PKCS12 file, so I've copied that and am calling (without knowing
what they do) SSLeay_add_all_algorithms and ERR_load_crypto_strings.
So, my code looks like this:
#include "openssl\applink.c" // copied from FAQ, don't know what it does
and then
CRYPTO_malloc_init(); // copied from FAQ, don't know what it does
SSLeay_add_all_algorithms(); // copied from sample code, don't know what
it does
ERR_load_crypto_strings(); // copied from sample code, don't know what
it does
FILE *file;
file = fopen( filename, "rb" );
if ( file != 0 )
{
PKCS12 *pkcs12 = d2i_PKCS12_fp( file, 0 ); // from the O'Reilly book
What's wrong with that please? And what documentation should I have found,
and where, that would have helped me get it right first time?
