Hi, Your patch is wrong: the flags CRYPT_NEWKEYSET and CRYPT_VERIFYCONTEXT can't be mixed and if they are set together like in your patch AcquireContext should return NTE_BAD_FLAGS. You can check that using the MS implementation under windows. It's also clearly stated in MSDN that CRYPT_VERIFYCONTEXT is reserved for non persistent operations which is not the case when you create a new container.
After witing a simple test I can confirm that, I filed a bug report against msn messenger, wonder what will happen with that.
