Random byte generation
Arguments
| :: Int | the number of bytes requested |
| -> IO ByteString |
Return a bytestring consisting of the given number of strongly random bytes
Arguments
| :: Int | the number of bytes requested |
| -> IO ByteString |
Return a bytestring consisting of the given number of pseudo random bytes
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.
