Searching for Messages Conforming to Arbitrary Sets of Conditions in SHA-256

, 2009
Recent progress in hash functions analysis has led to collisions on reduced versions of SHA-256. As in other hash functions, differential collision search methods of SHA-256 can be described by means of conditions on and between state and message bits.

Reversing Eight Rounds of SHA-256

This paper demonstrates a method to deterministically reverse the first eight rounds (iterations) of the SHA-256 compression function. By tracking the propagation of a single message schedule word through the internal state and expressing its effect algebraically across rounds, we isolate and recover its original value from the final state. The results

Instruction sequence expressions for the secure hash algorithm SHA-256

CoRR, 2013
The secure hash function SHA-256 is a function on bit strings. This means that its restriction to the bit strings of any given length can be computed by a finite instruction sequence that contains only instructions to set and get the content of Boolean registers, forward jump instructions, and a termination instruction.
