System.Entropy

Description

Obtain entropy from system sources. Currently, windows and *nix systems with a devurandom are supported.

Synopsis

Documentation

getEntropy :: Int -> IO ByteString

Inefficiently get a specific number of bytes of cryptographically secure random data using the system-specific facilities.

Use '/dev/urandom' on *nix and CryptAPI when on Windows. In short, this entropy is considered "cryptographically secure" but not true entropy.

data CryptHandle

Handle for manual resource mangement

hGetEntropy :: CryptHandle -> Int -> IO ByteString

Read random data from a CryptHandle
