random Source #

Arguments

:: Natural

Length of the result bytestring in bytes

-> IO ByteString 

Generate a random bytestring of length n. The PRNG is seeded from the system randomness source.

ioProperty $ ((fromIntegral n ===) . B.length) <$> random n
n > 4 ==> ioProperty $ (/=) <$> random n <*> random n

randomGen Source #

Arguments

:: GenIO

A PRNG that is used to generate random bytes.

-> Natural

Length of the result bytestring in bytes

-> IO ByteString 

Generate a random bytestring of length n using the given PRNG.
