Module sodiumoxide::crypto::stream::chacha20 [−] [src]

crypto_stream_chacha20 (Chacha20)

Structs

Key	`Key` for symmetric encryption
Nonce	`Nonce` for symmetric encryption

KEYBYTES	Number of bytes in a `Key`.
NONCEBYTES	Number of bytes in a `Nonce`.

gen_key	`gen_key()` randomly generates a key for symmetric encryption
gen_nonce	`gen_nonce()` randomly generates a nonce for symmetric encryption
stream	`stream()` produces a `len`-byte stream `c` as a function of a secret key `k` and a nonce `n`.
stream_xor	`stream_xor()` encrypts a message `m` using a secret key `k` and a nonce `n`. The `stream_xor()` function returns the ciphertext `c`.
stream_xor_inplace	`stream_xor_inplace` encrypts a message `m` using a secret key `k` and a nonce `n`. The `stream_xor_inplace()` function encrypts the message in place.
