Function Documentation

ascon_trng_generate()

int ascon_trng_generate	(	unsigned char *	out,
		size_t	outlen
	)

Generates a buffer of bytes from the system TRNG source.

Parameters

out	Output buffer to be filled with random bytes.
outlen	Length of the output buffer in bytes.

Returns

Non-zero if the system random number source is working; zero if there is no system random number source or it has failed.

This function should try to generate high quality random data even if it is a little slower.

ascon_trng_get_bytes()

int ascon_trng_get_bytes	(	unsigned char *	out,
		size_t	outlen
	)

Escape hatch that allows applications to provide their own interface to the system TRNG when the library does not know how to generate random bytes on its own.

Parameters

out	Buffer to fill with random bytes.
outlen	Number of bytes to provide.

Returns

Non-zero if the application provided the bytes or zero if the application does not know how to generate random bytes.
