void KEYGEN::init

(

int

lpin

)

Begin operation of the Algorythm and set the pin to be used for noise

Call this in setup(), before calling any other methods.

Parameters

lpin	integer value of the pin keyg.init(5);

Examples:

RANDOM.cpp, and RANDOM.ino.

void KEYGEN::gen_pass	(	void *	out,
		int	size
	)

Generate a password of specified size and stores it in the out pointer. The password includes characters from types NUMS , SYMS, CAPS, LOWE

Note

be sure that the out size is equal or greater that the size specidied.

Parameters

out	pointer that the generated password will be saved.
size	integer value, indicating the size of the password to be generated

Returns

No return value. the generated password is stored at the out pointer

Examples:

RANDOM.cpp, and RANDOM.ino.

void KEYGEN::gen_IV	(	void *	out,
		int	size
	)

Generate an IV of specified size and stores it in the out pointer. The IV is a numerical value.

Note

be sure that the out size is equal or greater that the size specidied.

Parameters

out	pointer that the generated IV will be saved.
size	integer value, indicating the size of the password to be generated

Returns

No return value. the generated IV is stored at the out pointer

Examples:

RANDOM.cpp, and RANDOM.ino.

int KEYGEN::get_type

(

)

return a random number from 0 to 3. This function is mainly used from gen_pass in order to randomlly get a character from NUMS or SYMS or CAPS or LOWE

Returns

returns an interger from 0 to 3

void KEYGEN::printArray	(	char	output[],
		int	sizel
	)

Gets an array and its size and prints it in the standard output character by character.

Parameters

output[]	array of any size.
sizel	integer values indicating the size of the array.

Returns

No return value.

Examples:

RANDOM.cpp, and RANDOM.ino.

double KEYGEN::millis

(

)

used in linux in order to retrieve the time in milliseconds.

Returns

returns the milliseconds in a double format.

long int KEYGEN::rpi_rand

(

int

x

)

used in Raspberry pi in order to generate a random number.

Note

there is a definition in KEYGEN_config that defined random(x) as rpi_rand(x).

Parameters

x	get an integer that is te upper limit-1 of the random number.

Returns

returns a random number from 0 to x
