According to a csdn report, Wang Xiaoyun, a Chinese mathematician, proposed an algorithm on crypto 2004 that can successfully crack MD5. Both gigix and Wang Xiong quoted related reports in their blog. MD5 is a digest algorithm, so it is

(a) Why do I use hash functions to encrypt passwords If you need to save a password (such as a website user's password), you should consider how to protect the password data, and it is extremely unsafe to write the password directly to the database
