At this week's Crypto 2004 conference in California, several papers were presented that demonstrated vulnerabilities in algorithms that are often used to create digital signatures. Although the results are preliminary, many in the security community are concerned about what such weaknesses might mean for digital signature use in the future. The algorithms in question are MD5, with is often used with digital signatures, as well as SHA-0 and SHA-1, both popular in security development.


MD5 cracked by Xiaoyun Wang, et. al, not Antoine Joux

There is an error in attribution. Antoine Joux broke SHA-0, Xiaoyun Wang et al. broke MD5 (as well as RIPEMD, HAVAL-128, and for kicks, they simplified MD4 collisions to the point where they can be calculated by hand).
