But we advise if you are using OpenPGP or S / MIME for electronic mail encoding , you should fleetly notice option for unattackable remnant - to - death communicating .
Sebastian Schinzel , a Centennial State - source of the novel field has convey that encrypt e-mail are no longer good .

farsighted Term Solution
The standard demand to be update .
There is no direction we can go forward seamlessly after roll in the hay about these .
These flaw are imbed deep into the behaviour of PGP and S / MIME , and thus expert will have to derive onward and patch up them for good .
Until there is a lasting solvent , we can practice the strategy yield .
