ocrypto_chacha20_poly1305_update_enc()

void ocrypto_chacha20_poly1305_update_enc	(	ocrypto_chacha20_poly1305_ctx *	ctx,
		uint8_t *	c,
		const uint8_t *	m,
		size_t	m_len
	)

#include <crypto/nrf_oberon/include/ocrypto_chacha20_poly1305.h>

ChaCha20-Poly1305 incremental encoder input.

The generator state ctx is updated to include a message chunk m.

This function can be called repeatedly on arbitrarily small chunks of the message until the whole message has been processed.

Parameters

	ctx	Generator state.
[out]	c	Generated ciphertext. Same length as input message.
	m	Message chunk.
	m_len	Length of m.

Remarks

Initialization of the generator state ctx through ocrypto_chacha20_poly1305_init is required before this function can be called.

ocrypto_chacha20_poly1305_update_enc must be called after any call to ocrypto_chacha20_poly1305_update_aad.

c may be same as m.
