-> keythe key (128 or 256 bits)
-> noncethe nonce (64 or 96 bits)
-> Statethe initial ChaCha state
Initialize a new ChaCha context with the number of rounds, the key and the nonce associated.
initializeX :: (ByteArrayAccess key, ByteArrayAccess nonce)=> Intnumber of rounds (8,12,20)
-> keythe key (256 bits)
-> noncethe nonce (192 bits)
-> Statethe initial ChaCha state
Initialize a new XChaCha context with the number of rounds, the key and the nonce associated.
An XChaCha state can be used like a regular ChaCha state after initialisation.
combine Combine the chacha output and an arbitrary message with a xor, and return the combined output and the new state.
generate Generate a number of bytes from the ChaCha output directly
ChaCha context
Initialize simple ChaCha State
The seed need to be at least 40 bytes long
similar to generate but assume certains values
ChaCha context for DRG purpose (see Crypto.Random.ChaChaDRG)
