TAIPEI—In five years, the U.S. government will cease to use SHA-1 (Secure Hash Algorithm) and convert to a new and more advanced computer data encryption, according to the article "Security Cracked!" from New Scientist . The reason for this change is that 41-years old associate professor Wang Xiaoyun of Beijing's Tsinghua University and Shandong University of Technology has already cracked SHA-1.
According to a Beijing digest, this SHA-1 encryption includes the world's gold standard Message-Digest algorithm 5 (MD5). Before Professor Wang cracked it, the MD5 could only be deciphered by today's fastest supercomputer running codes for more than a million years.
However, professor Wang Xiaoyun, a graduate of Shandong University of Technology's mathematics department, and her research team obtained results by using ordinary personal computers.
WTF, the full history here.
