HH2AA has not been issued an official SuperFox key.
As we have stated publicly before, security of these keys is not
consistent with highest cryptographic standards. Most people will not
be able to crack the key algorithm, but several have already proved that
a dedicated hacker can do so.
From our first thinking about a possible SuperFox mode, we have known
this weakness to be a potential problem and the main reason why we
consider the present approach experimental and temporary. It has the
additional issue that small parts of the code must remain secret, which
is contrary to our normal open-source policy and complicates program
licensing.
We are working to develop a security system that will meet high
cryptographic standards and can be based entirely on open-source code.
We already have some ideas, but anyone skilled in this area is welcome
to write to us -- either privately or on one of the relevant WSJT email
lists -- with specific proposals.
