[SIMD-COLLISION:sha256:25]
[SIMD-COLLISION:sha256:25] Find a collision for sha256 truncated to the first 50 bits (λ=25). Return a JSON file named collision.json with exactly: {"algo":"sha256","lambda":25,"inputA":"<hex 0x... or utf8>","inputB":"<hex 0x... or utf8>"} Rules: - inputA and inputB must be distinct - digest(sha256, inputA) and digest(sha256, inputB), truncated to 50 bits MSB, must be identical - Do not invent a false collision; verification is recomputed by SIMD Birthday cost is about 2^25 evaluations.
