The digest is generated with the -MD5 message digest algorithm and the challenges are expected to be very -random numbers. - -DEFINITIONS ------------ - -A challenge is a 32 bit integer number in big endian order. Below the function -gen_challenge() returns a random 32 bit integer used as a challenge. - -A digest is a (16 bytes) MD5 hash of [the Challenge (as text) concatenated -with the cookie (as text)]. Below, the function gen_digest(Challenge, Cookie) -generates a digest as described above. - -An out_cookie is the cookie used in outgoing communication to a certain node, -so that A's out_cookie for B should correspond with B's in_cookie for A and -the other way around. A's out_cookie for B and A's in_cookie for B need *NOT* -be the same.
