WebSHA-2 is actually four functions: SHA-224, SHA-256, SHA-384, and SHA-512. On 12 August 2004, Joux, Carribault, Lemuet, and Jalby announced collisions in SHA-0. On 17 August … WebSHA-256, we show that the low probability of a single local collision may give rise to a false sense of security. 1 Introduction After recent cryptanalytic results on MD5 [20], SHA-1 [2,15,19] and similar hash functions, the resistance of members of the SHA-2 family (i.e. SHA-224, SHA-256, SHA-384 and SHA-512) [13] against recent attacks is an ...
