## 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.
