Factors Found in 200-Digit RSA Challenge

Posted by Zonk on Tuesday May 10, 2005 @08:44AM from the really-big-numbers dept.

diodesign writes "The two unique prime factors of a 200-digit number have been discovered by researchers at Bonn University (Germany) and the CWI (Netherlands). The number is the largest integer yet factored with a general purpose algorithm and was one of a series of such numbers issued as a challenge by security company RSA security in March 1991 in order to track the real-world difficulty of factoring such numbers, used in the public-key encryption algorithm RSA. RSA-200 beats the previous record number 11281+1 (176 digits, factored on May 2nd, 2005), and RSA-576 (174 digits, factored on December 3rd, 2003)."

Wow , someone had the guts to mod a 56 UID as a troll (of course the fact that the post does not seem to be in anyway a troll, so the moderator was brave and stupid). Serioulsy whats so wrong with the parent post to mark it as a troll? It does not seem absurd to wish for unbounded length ints (BigInteger?).
