	Fill the slot; blocks for the base point multiply.

int	consume_spare_ephemeral (NoiseHandshakeState *state)
	Move the key pair into a handshake that has not started and wipe the slot; 0 unless noise-c rejects it.

◆ psk_t

using esphome::noise::psk_t = std::array<uint8_t, 32>

Definition at line 14 of file noise.h.

Function Documentation

◆ consume_spare_ephemeral()

int esphome::noise::consume_spare_ephemeral ( NoiseHandshakeState * state )

Move the key pair into a handshake that has not started and wipe the slot; 0 unless noise-c rejects it.

Definition at line 46 of file noise.cpp.

◆ ESPHOME_LOG_TAG()

esphome::noise::ESPHOME_LOG_TAG	(	TAG	,
		"noise"	)

◆ format_reject_payload()

size_t esphome::noise::format_reject_payload	(	uint8_t *	buf,
		size_t	capacity,
		const LogString *	reason )

Fill buf with a handshake reject payload (status byte plus the reason text, PROGMEM aware); returns the payload length.

buf needs capacity for the status byte plus the truncated reason.

Definition at line 100 of file noise.cpp.

◆ has_spare_ephemeral()

bool esphome::noise::has_spare_ephemeral ( )

inline

Definition at line 52 of file noise.h.

◆ noise_err_to_logstr()

const LogString * esphome::noise::noise_err_to_logstr ( int err )

Convert a noise error code to a readable error.

Definition at line 58 of file noise.cpp.

◆ noise_rand_bytes()

void esphome::noise::noise_rand_bytes	(	void *	output,
		size_t	len )

Definition at line 146 of file noise_handshake.cpp.

◆ prepare_spare_ephemeral()

void esphome::noise::prepare_spare_ephemeral ( )

Fill the slot; blocks for the base point multiply.

Definition at line 31 of file noise.cpp.

◆ reject_reason_for()

const LogString * esphome::noise::reject_reason_for ( int err )

Reject reason for a failed handshake read.

The MAC failure string is a wire contract: clients match it to report a wrong key.

Definition at line 96 of file noise.cpp.

◆ write_frame_header()

void esphome::noise::write_frame_header	(	uint8_t *	buf,
		uint16_t	payload_len )

inline

Definition at line 70 of file noise.h.

Variable Documentation

◆ spare_ephemeral

uint8_t esphome::noise::spare_ephemeral
