November 8, 2005--A team at the German Federal Agency=20
for Information Technology Security (BSI) recently=20
announced the factorization of the 193-digit number=20

known as RSA-640. The team responsible for this=20
factorization is the same one that previously factored=20
the 174-digit number known as RSA-576 (MathWorld=20
headline news, December 5, 2003) and the 200-digit=20
number known as RSA-200 (MathWorld headline news,=20
