Random byte generation

randBytes

Arguments

:: Int

the number of bytes requested

-> IO ByteString

Return a bytestring consisting of the given number of strongly random bytes

prandBytes

Arguments

:: Int

the number of bytes requested

-> IO ByteString

Return a bytestring consisting of the given number of pseudo random bytes

add

Arguments

:: ByteString

random data to be added to the pool

-> Int

the number of bits of entropy in the first argument

-> IO ()

Add data to the entropy pool. It's safe to add sensitive information (e.g. user passwords etc) to the pool. Also, adding data with an entropy of 0 can never hurt.
