How To Recover Message
Compute s=1/3(2(p-1)(q-1)+1) then
compute Cs = Kr×c + T
* That is …
   The remainders (C) raised to s power equal
Kr times some (quotient) c no one cares
about plus the original clear text number!
So, raise the remainders to s, divide by Kr
and PRESTO! the new remainder is the
answer
