Hi there.
I guess my problem is really related to verify callback
on SSL_CTX_set_verify function.
I just add to my code a
dummy callback returning 1 and everything works properly.
int verify_callback
(int ok, X509_STORE_CTX *ctx);
int verify_callback (int ok,
X509_STORE_CTX *ctx)
{
printf("Verification callback OK!\n");
return 1;
}
...
SSL_CTX_set_verify(ssl_server_ctx,
SSL_VERIFY_PEER | SSL_VERIFY_FAIL_IF_NO_PEER_CERT,
dtls_verify_callback);
...
The problem is that error don't tell much information about
what's really going on or what's really missing.
Thanks for your help.
Now you've effectively disabled all security :)
Try adding this to the verify_callback
static int verify_callback(int ok, X509_STORE_CTX *ctx)
{
X509 *cert = NULL;
char *cert_DN = NULL;
printf("ok = %d\n", ok);
cert = X509_STORE_CTX_get_current_cert(ctx);
cert_DN = X509_NAME_oneline( X509_get_subject_name( cert ),
NULL, 0 );
printf( "cert DN: %s\n", cert_DN);
}
that way, you will know whether your server is processing the right
certificate chain.
HTH,
