We provide a collision attack and preimage attacks on the MDC-2 construction, which is a method (dating back to 1988) of turning an n-bit block cipher into a 2n-bit hash function. ...

Hamsi is one of the 14 second-stage candidates in NIST’s SHA-3 competition. The only previous attack on this hash function was a very marginal attack on its 256-bit version publi...
