I suspect what the above is actually referring to is the key recovery
mechanism present in ``PGP for Business Security'' (and possibly other
commercial PGP-ish products), and perhaps other such "features".
these are not, repeat NOT, any sort of practical (computable) key-crack
algorithm --- the discovery of which, as has already been pointed out,
would be worthy of a Field Prize (the closest thing there is to a
mathematics Nobel Prize).
and also the ``comp.risks'' archives.
b.t.w., PGP does not "solve" the problem of traffic analysis (e.g.,
knowing which sites/persons have exchanged phone/FAX/net(/e-mail)).
