initialize

Arguments

:: (ByteArrayAccess key, ByteArrayAccess nonce) |
=> Int | number of rounds (8,12,20)
-> key | the key (128 or 256 bits)
-> nonce | the nonce (64 or 96 bits)
-> State | the initial Salsa state

Initialize a new Salsa context with the number of rounds, the key and the nonce associated.

combine

Arguments

:: ByteArray ba |
=> State | the current Salsa state
-> ba | the source to xor with the generator
-> (ba, State) |

Combine the salsa output and an arbitrary message with a xor, and return the combined output and the new state.

generate

Arguments

:: ByteArray ba |
=> State | the current Salsa state
-> Int | the length of data to generate
-> (ba, State) |

Generate a number of bytes from the Salsa output directly

data State

Salsa context
