New Records in Collision Attacks on RIPEMD-160 and SHA-256

ePrint Report: New Records in Collision Attacks on RIPEMD-160 and SHA-256

Yingxin Li, Fukang Liu, Gaoli Wang

RIPEMD-160 and SHA-256 are two hash functions used to generate the bitcoin address. In particular, RIPEMD-160 is an ISO/IEC standard and SHA-256 has been widely used in the world. Due to their complex designs, the progress to find (semi-free-start) collisions for the two hash functions is slow. Recently at EUROCRYPT 2023, Liu et al. presented the first collision attack on 36 steps of …
