WebMay 21, 2024 · But we also don’t brute-force a 128-bit long number one-by-one. Instead, we can brute-force the coefficient byte-by-byte. For example, when we want to know 2467 * x = 3584551, we don't need to brute-force the number from 1 to 99999. We can first brute-force the last digit: 2467 * 3 = 7401, which has the same last digit with the result.
