MD5 Collisions...



Hi everyone,

Not sure if you've read http://www.win.tue.nl/hashclash/SoftIntCodeSign/ .

should some kind of advisory be sent to advise people not to rely solely on MD5 checksums? Maybe an update to the man page is due ? :

"
MD5 has not yet (2001-09-03) been broken, but sufficient attacks have
been made that its security is in some doubt. The attacks on MD5 are in
the nature of finding ``collisions'' -- that is, multiple inputs which
hash to the same value; it is still unlikely for an attacker to be able
to determine the exact original input given a hash value.
"

Cheers,
B

If you find a solution and become attached to it, the solution may become your next problem.
