Code for MD4/5 collisions released

The code needed to create two bitstreams with the same hash is public. It takes about 45 minutes to find a MD5 collision. This does not allow to create a bitstream which maps to a given hash, so md5 is still safe for signing cleartext. However you can make two different documents in PostScript/PDF which have the same hash (more details). Use SHA-256 or SHA-512 (not SHA-1). MD5 collisions could also be used as "watermarks" for mp3 files (players skip invalid data) to track their distribution on p2p networks.
As consoles are becoming more

Once online games started crowding the market, open source networks, such as the Dreamcast, PlayStation 2, Nintendo GameCube and Xbox took advantage of online functionality with its PC game counterpart. Games such as Phantasy Star Online have private servers that function on multiple consoles. Dreamcast, PC, Macintosh and GameCube players are able to share one server. Earlier games, like 4x4 Evolution, Quake III and Need for Speed: Underground also have a similar function with consoles able to interact with PC users using the same server. Usually, a company like Electronic Arts or Sega runs the servers until it becomes inactive, in which private servers with their own DNS number can function. This form of open source networking has a small advantage over the new generation of Sony and Microsoft consoles which customize their servers to the consumer. giochi gratis, Hachi, Missione Alfa, WoW Connection Entry, Car Girls, Neo Revenge,
