 * This program gathers some random bits of data and used the MD5
 * message-digest algorithm to generate a 128-bit hexadecimal number for
 * use with xauth(1).
 *
 * NOTE: Unless /dev/random is available, this program does not actually
 * gather 128 bits of random information, so the magic cookie generated
 * will be considerably easier to guess than one might expect.
