RIPEMD 160 GoLang Implementation - Compression

Step 1: Initialization of Working Variables RIPEMD-160 starts by initializing two parallel computation paths. Each path uses five working variables (a–e on one side, aa–ee on the other). Both paths begin with the same initial values, defined by Dobbertin et al. Step 2: Mutation and Compression This is where the “fun” begins — the heart of RIPEMD-160. The compression function runs for 80 steps, divided into 5 rounds of 16 steps each. Each round computes a temporary word on both sides of the algorithm (left and right). The words are calculated using: Logical functions (XOR, AND, OR, NOT). Bit rotations (left shifts by specific values). Constants defined by the algorithm. After computing the temporary word, the working variables are rotated and mutated. Step 3: Computing Chaining Variables After completing all 80 steps, the two computation paths are recombined. The chaining values are updated by adding results from both sides back into the hash state.
