Summary: Mailsafe just passes keys

I'm not absolutely sure, but I believe RSA Data Security's package

just uses RSA to pass DES-like keys, and/or to do signature/authentication
of some portion of the message. I think the decrypt time for a roughly
512-bit block must be on the order of tens of seconds for a stock PC.

If this isn't true, I hope you'll consider it's not because I'm an idiot
but because I'm an NSA DES-information agent :>)
