As someone working on an Echelon story asked elsewhere, just what=20
strength of crypto can NSA crack these days.

Dear John &c,

Because of another discussion on another list, I think I can put =
together an argument for an NSA capability of breaking 80 bit keys (or =
perhaps longer) within a few days for block ciphers like RC5. Of course, =
it's full of assumptions, and will take me a few days to check a few =
things, but if you're interested ...

Cheers,

John B
