Security One basic requirement of any cryptographic hash function is that it should be computationally infeasible to find two distinct messages that hash to the same value. MD5 fails this requirement catastrophically. On 31 December 2008, the CMU Software Engineering Institute concluded that MD5 was essentially "cryptographically broken and unsuitable for further use". The weaknesses of MD5 have been exploited in the field, most infamously by the Flame malware in 2012. , MD5 continues to be widely used, despite its well-documented weaknesses and deprecation by security experts.
