So with about 1 000 000 USD and a full year you would get 122 bits
already now and agencies have a bit more budget than this! Furthermore,
the algorithm parallelizes extremely well and can handle a batch of 100
targets at only 10 times the cost.
No it cannot handle a bunch of a hundred targets at only ten times the
cost. It is already parallelized. A hundred targets is a hundred times
the cost.
But let us not think small. Suppose the president says "Break James
Donald's key. I don't care how much it costs. The sky is the limit"
and they devote the entire US gross national product for a year to
breaking James Donald's key in a year.
Then they can break a 170 bit key.
But I rather doubt that they will.
