Precomputation for Rainbow Tables has Never Been so Fastms with a 128-core computer perfectly match the theoretical expectations. We construct a rainbow table for a space . in approximately 8?h instead of 50?h for the usual way to generate a table. We also show that the efficiency of our technique is very close from the theoretical time lower bound.作者: 敲竹杠 時間: 2025-3-22 00:43 作者: 擁護(hù)者 時間: 2025-3-22 05:15 作者: ureter 時間: 2025-3-22 11:34 作者: 食料 時間: 2025-3-22 16:07 作者: 食料 時間: 2025-3-22 19:09
