Bidzos may not need to worry about this or ask damages for loss of export
status, if Michael Ernst spoke to the right people for the attached msg.

The RC4 algorithm is also unpublished and also exportable at 40-bit key
strength. A couple of weeks ago I asked NSA whether just RSADSI, or both
NSA and RSADSI, want to keep the algorithm secret. NSA told me that they
would be delighted to see the algorithm published, but that RSADSI wanted
to keep it a trade secret, presumably to protect their intellectual property.
Given the parties involved, extra disclaimers must apply.
