int sgeGetDistance	(	int	x,
		int	y,
		int	xx,
		int	yy
	)

get the distance of two coordinates

Parameters:

x	x position of point 1
y	y position of point 1
XX	x position of point 2
yy	y position of point 2

Returns:

the distance of the two points

char* sgeMD5	(	const unsigned char *	data,
		unsigned int	datalen
	)

get a md5 sum from data

Parameters:

data	a unsigned char pointer to your data
datalen	the length in bytes of your data

Returns:

a new allocated char * pointer representing the hex string of the md5

example:

 const char testtext[]="some text";

 char *md5=sgeMD5((const unsigned char *)testtext, (unsigned int) strlen(testtext));
 printf("%s\n",md5);
 sgeFree(md5);

char* sgeSHA1	(	const unsigned char *	data,
		unsigned int	datalen
	)

get a sha1 hash from data

Parameters:

data	a unsigned char pointer to your data
datalen	the length in bytes of your data

Returns:

a new allocated char * pointer representing the hex string of the sha1

example:

 char *sha1=sgeSHA1((const unsigned char *)testtext, (unsigned int) strlen(testtext));
 printf("%s\n",sha1);
 sgeFree(sha1);
