System.Entropy

Description

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

Synopsis

Documentation

getEntropy :: Int -> IO ByteStringSource

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 Source

Handle for manual resource mangement

hGetEntropy :: CryptHandle -> Int -> IO ByteStringSource

Read random data from a CryptHandle
