Lol, to a non existent group *again!*

(Incoming clue by 4: there is no group called dev.null, dev is not a
valid top level organisation)
You need a better provider, it exists here or it would complain of an
unresolved group.

No, it doesn't. You can't even copy the name correctly.



Be fair, it *was* ROTted. :-)

Next time, make it harder, used double ROT13 ;-)

Task you should know from the DES experience that when DES was found to be
weak a stab at 2DES was taken without much improvement. It was therefore
necessary to adopt 3DES. Hence 3ROT13 must be the best algorithm.


it was always rumoured that the NSA watered down the original proposed
standard for DES from 64 to 56 bits...


IIRC, it has recently been shown that the changes to DES suggested by
the NSA actually made it stronger.


Yeah, the NSA did a press release to that effect. Its still a little
confusing since they supposedly strengthened the so called S boxes, but
were relatively silent about why they lobbied for a reduction in key
length.
