Crypto.Random.AESCtr
Description
this CPRNG is an AES based counter system.
the internal size of fields are: 16 bytes IV, 16 bytes counter, 32 bytes key
each block are generated the following way:
aes (IV xor counter) -> 16 bytes output
Synopsis
- data AESRNG
- make :: EntropyPool -> AESRNG
- makeSystem :: IO AESRNG
Documentation
AES Counter mode Pseudo random generator.
Provide a very good Cryptographic pseudo random generator that create pseudo random output based an AES cipher used in counter mode, initialized from random key, random IV and random nonce.
This CPRG uses 64 bytes of pure entropy to create its random state.
By default, this generator will automatically reseed after generating 1 megabyte of data.

make :: EntropyPool -> AESRNG Source #
make an AES RNG from an EntropyPool.
use makeSystem to not have to deal with the entropy pool.
makeSystem :: IO AESRNG Source #
Initialize a new AES RNG using the system entropy. {-# DEPRECATED makeSystem "use cprgCreate with an entropy pool" #-}
