Function Documentation

void aead_random_finish

(

void

)

Finishes using the random number source.

If the random API has internal state, then this function will destroy the internal state to protect forward secrecy.

uint32_t aead_random_generate_32

(

void

)

Generates a single random 32-bit word.

Returns

The random word.

void aead_random_generate_32_multiple	(	uint32_t *	out,
		unsigned	count
	)

Generates multiple random 32-bit words for masking purposes.

Parameters

out	Output buffer to receive the words.
count	Number of words to generate.

uint64_t aead_random_generate_64

(

void

)

Generates a single random 64-bit word.

Returns

The random word.

void aead_random_generate_64_multiple	(	uint64_t *	out,
		unsigned	count
	)

Generates multiple random 64-bit words for masking purposes.

Parameters

out	Output buffer to receive the words.
count	Number of words to generate.
