Abstract
RC4-Hash is a variable digest length cryptographic hash function based on the design of the RC4 stream cipher. In this paper, we show that RC4-Hash is not collision resistant. Collisions for any digest length can be found with an expected effort of less than 29 compression function evaluations. This is extended to multicollisions for RC4-Hash. Finding a set of 2k colliding messages has an expected cost of 27 + k·28 compression function evaluations.
