Researching on MD5's characteristics based on software reversing

Recognizing message digest algorithm 5 (MD5 algorithm) from binary files plays an important role in finding malicious code and protecting computer system. Based on analysis result of the basic concept of MD5 algorithm, this paper researches their software reversing characters, and gives analysis of typical examples in detail. Researching conclusion of this paper can provide important information in recognizing MD5 algorithm from binary files.
