Description

BN - multiprecision integer arithmetics

Synopsis

Type

data BigNum Source

BigNum is an opaque object representing a big number.

Allocation

allocaBN :: (BigNum -> IO a) -> IO a Source

allocaBN f allocates a BigNum and computes f. Then it frees the BigNum.

withBN :: Integer -> (BigNum -> IO a) -> IO a Source

withBN n f converts n to a BigNum and computes f. Then it frees the BigNum.

newBN :: Integer -> IO BigNum Source

This is an alias to integerToBN.

Conversion from/to Integer

peekBN :: BigNum -> IO Integer Source

This is an alias to bnToInteger.

integerToBN :: Integer -> IO BigNum Source

This is a GHC specific, fast conversion between Integers and OpenSSL bignums. It returns a malloced BigNum.

bnToInteger :: BigNum -> IO Integer Source

Convert a BIGNUM to an Integer

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 m computes a to the p-th power modulo m.

Random number generation

randIntegerUptoNMinusOneSuchThat Source

:: Integer -> Bool a filter function -> Integer one plus the upper limit -> IO Integer Return a strongly random number in the range 0 <= x < n where the given filter function returns true.

prandIntegerUptoNMinusOneSuchThat Source

:: Integer -> Bool a filter function -> Integer one plus the upper limit -> IO Integer 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

randIntegerOneToNMinusOne :: Integer -> IO Integer Source

Return a strongly random number in the range 0 < x < n

prandIntegerOneToNMinusOne :: Integer -> IO Integer Source

Return a random number in the range 0 < x < n
