Detailed Description

Classes for Salsa and Salsa20 stream ciphers.

Definition in file salsa.h.

Function Documentation

Salsa20_Core()

void Salsa20_Core	(	word32 *	data,
		unsigned int	rounds
	)

Salsa20 core transform.

Parameters

data	the data to transform
rounds	the number of rounds

Several algorithms, like CryptoBox and Scrypt, require access to the core Salsa20 transform. The current Crypto++ implementation does not lend itself to disgorging the Salsa20 cipher from the Salsa20 core transform. Instead Salsa20_Core is provided with customary accelerations.
