If you reread my post I edited it 
Something is going wrong before the CryptExportKey() call.

I am using KEYLENGTH|CRYPT_EXPORTABLE flag in CryptDeriveKey()....I should have mentioned in my earlier posting.
So do you mean the key is getting corrupted some where after CryptDeriveKey() and before CryptExportKey()? I have been debugging the code but cant find this?

That's what I first thought until I reread your post (once again, I apparently can't read)
and noticed the PUBLICKEYBLOB type. You probably need to use SIMPLEBLOB since CryptDeriveKey
creates a session key, not a public key.

Wait. Try CryptExportKey with SIMPLEBLOB instead of PUBLICKEYBLOB 
Sorry for the confusion!

I am using PUBLICKEYBLOB since this function allows mee to export the key with out the handle to a cryptographic key of the destination user
|
|

|

Right but I don't think that will work on a session key.

So What do I do for exporting the session key? I dont have the destination users CSP container or key

Don't you know honey attracts bears?!?

Does your intent a tools for increase security of network?

MFC may or may not be the best tool (likely not) to build a honeypot, but this depends on the kind of honeypot you are trying to build. Are you trying to build something to attract and track the activity of a so-called "blackhat"? Or something that basically is a spam-poisoning honeypot/spamtrap? Etc.
There are quite a few different kinds of honeypots available recently, so it should be rather easy to Google for something to look at and/or play around with.
Peace!

I googled but i didnt get any sources and I want to track their activity.

Its an answer to me or to sender?;P

Yes I am planning to increase security of network and I want to attract the attackers and track them.

I was trying to to search about it but I can't search (but I must say a thing to you before use of them read a lot of articles about them they have preferences and defects)

I want to design a new honey pot but not to use the existing one.

I dont know why you got low votes but I give you 5 because I know your knowledge programming is very good

Probably because the OP was referring to this, but I replied otherwise. That's the price you pay for asking short, ambiguous questions.

I seen this in a PHP script the other day.
switch($base){<br />
case $a == 'a' || $b == 'd':<br />
break;<br />
}
I've never seen this before in C++ development, is it valid syntax?
I could have swore I tried it once in VC++ and it failed cause CASE requested a CONSTANT?
Is this in the ANSI C/C++ spec?
I'm finding the only constant in software development is change it self.

this works in PHP, because there isn't anything constant, if you would use variables in C++ an multiselection can occur.
So, i didn'd know any way to use code like this in C++.

I remember that some years ago I worked on a project and used:
switch($base){
case $a == 'a':
case $b == 'd':
{
make your things here
break
}
case $a == ... :
}
hope this helps...
PS: I've used that in C++ but in ms-dos, I suppose that the compiler still remember this syntax...

case expressions in C have to be integral constants.
|
|
|
|

I looked into the EBNF for C/C++ and it appears (from what I can tell) that is the case (np pun intended) for both languages and apparently C# as well?
I'm finding the only constant in software development is change it self.
