Reply #9: Even encryption's fallible [View All]

Couple that with the fact that everyone he emails would have to have the key to decrypt it (and know how to do that!) and access to it would probably become an open secret to an obsessed-enough reporter soon enough.

You'd also have the potential issue in that case of the president sending encrypted messages out of the White House, which would open up all sorts of cans.
