[ExI] You'd better sell your bitcoins

[Keith Henson]

I don't know how the SWIFT network is secured.  Long ago, it was DES,
but John Gilmore built a cracking machine and showed how easy it was
to brute force crack.  I think they went to triple DES which is 56 x 3
bits.  If quantum computers can crack the SWIFT network (I don't
know), I think that would be a much larger problem than Bitcoin.

Anyone know?
