void	ocrypto_chacha20_encode (uint8_t *c, const uint8_t *m, size_t m_len, const uint8_t *n, size_t n_len, const uint8_t key[(32)], uint32_t count)
Incremental ChaCha20 Encoder.
This group of functions can be used to incrementally compute the ChaCha20 encryption for a given message and key, by segmenting a message into smaller chunks. Use pattern: Encoding/Decoding: ocrypto_chacha20_init(ctx, n, n_len, key, count); ocrypto_chacha20_update(ctx, c, m, m_len); ... ocrypto_chacha20_update(ctx, c, m, m_len);
void	ocrypto_chacha20_init (ocrypto_chacha20_ctx *ctx, const uint8_t *n, size_t n_len, const uint8_t key[(32)], uint32_t count)
void	ocrypto_chacha20_update (ocrypto_chacha20_ctx *ctx, uint8_t *c, const uint8_t *m, size_t m_len)
