Function Documentation

random_nonce()

void random_nonce	(	unsigned char *	buf,
		size_t	size )

Fill a buffer with random bytes.

The bytes are not cryptographically random enough to be used in a key, but they should be good enough for a nonce or boundary string that may be sent in cleartext.

If CONFIG_SSL is defined, then this function is instead defined in src/network/ssl/ssl.c, and it gets random numbers directly from the selected SSL library.
