Web1 Collisions for MD5 MD5 is the hash function designed by Ron Rivest [9] as a strengthened version of MD4 [8]. 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 WebHMAC The cryptanalysis of HMAC-MD5 is usually conducted together with NMAC (Nested MAC) since they are closely related. NMAC uses two independent keys K1 and K2 such that NMAC (K1, K2, M) = H (K1, H (K2, M), where K1 and K2 are used as secret IVs for hash function H (IV, M).
