MD5 Collision Source Code Released，这位大牛把王小云女士的论文用C代码实现出来了，并且速度要远远超过原来王小云在论文中预估实现的时间。在这位大牛的运行环境（P4 1.6G）下，md4可以实现秒杀，md5也只不过是耗费了区区 45 分钟而已。

SiliconEntity writes "The crypto world was shaken to its roots last year with the announcement of a new algorithm to find collisions in the still widely-used MD5 hash algorithm. Despite considerable work and commentary since then, no source code for finding such collisions has been published. Until today! Patrick Stach has announced the availability of his source code for finding MD5 collisions and MD4 collisions (Coral cache links provided to prevent slashdotting). MD4 collisions can be found in a few seconds (but nobody uses that any more), while MD5 collisions (still being used!) take 45 minutes on a 1.6 GHz P4. At last we will be able to implement various attacks which have been purely hypothetical until now. This more than anything should be the final stake in the heart of MD5, now that anyone can generate collisions whenever they want."

Could we convert it to java, Smile.
