(

x)

do { if ((x) != NULL) {free(x); x=NULL;} } while(0)

Free memory if the pointer and zero the pointer.

Note

You are explicitly allowed to pass NULL pointers – they will always be ignored.

void hmac_md5_final	(	uchar *	digest,
		HMACMD5Context *	ctx
	)

Finish off hmac_md5 "inner" buffer and generate outer one.

void hmac_md5_init_limK_to_64	(	const uchar *	key,
		int	key_len,
		HMACMD5Context *	ctx
	)

The microsoft version of hmac_md5 initialisation.

void hmac_md5_init_rfc2104	(	uchar *	key,
		int	key_len,
		HMACMD5Context *	ctx
	)

The rfc 2104 version of hmac_md5 initialisation.

void hmac_md5_update	(	const uchar *	text,
		int	text_len,
		HMACMD5Context *	ctx
	)

Update hmac_md5 "inner" buffer.
