In 1993 Bert den Boer and Antoon Bosselaers [1] found pseudo-collision for MD5 which is made of the same message with two different sets of initial value. H. Dobbertin[3] found a free-start collision which consists of two different 512-bit Webproposed [19,20]. For example, distinguishing attacks on HMAC/NMAC-MD5 and MD5-MAC were proposed in [20]. The inner near-collisions are used in the distinguisher which reveals more information than inner collisions. In the same work, they were able to recover partial subkey of the MD5-MAC as well. 1 by Zheng Yuan, Keting Jia, Wei Wang, and ... highly organized person meaning
