.Net: Will my RSA keys still function after August 2012?

Question

I just read this article RSA keys under 1024 bits are blocked, and in my .NET software I make extensive use of 384bit keys. Will my program still be able to generate/store/read keys from the MachineKeyStore using the RSACryptoServiceProvider? Or will I be forced to send out a patch?

Answer 1

I got a reply from Microsft (Kurt L Hudson), and this update should only affect chainbuilding, so it seems RSACryptoServiceProvider will continue to function with small keysizes after August 2012.
