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