Type
Allocation
Conversion from/to Integer
integerToBN :: Integer -> IO BigNum Source #
This is a GHC specific, fast conversion between Integers and OpenSSL bignums. It returns a malloced BigNum.
integerToMPI :: Integer -> IO ByteString Source #
Convert an Integer to an MPI. See bnToMPI for the format
mpiToInteger :: ByteString -> IO Integer Source #
Convert an MPI to an Integer. See bnToMPI for the format
Computation
modexp :: Integer -> Integer -> Integer -> Integer Source #
modexp a p ma to the p-th power modulo m.
Random number generation
randIntegerUptoNMinusOneSuchThat Source #
Return a strongly random number in the range 0 <= x < n where the given filter function returns true.
prandIntegerUptoNMinusOneSuchThat Source #
Return a random number in the range 0 <= x < n where the given filter function returns true.
randIntegerZeroToNMinusOne :: Integer -> IO Integer Source #
Return a strongly random number in the range 0 <= x < n
prandIntegerZeroToNMinusOne :: Integer -> IO Integer Source #
Return a random number in the range 0 <= x < n
