How to defend against hardware breakpoints-debugging registers

written by hardware or executed; whether it is a byte, a pair of words, or a pair of words. Okay. you may understand something here. 1. Why is there only four hardware breakpoints in OD?2. Why are there byte, word, and DWORD in the hardware breakpoint?3. Why are there read, write, and execution points for the hardware breakpoint?Ii. Differences between F4, F8, F7, and F2 In the help of ollydbug, I only mentioned how to use F7 and F8, and did not explain their implementation principles. Now let'

Several shortest paths for hash algorithms

distance from startpoint (SP) to endpoint (EP) is certain, so we can write a valuation function to estimate the shortest distance from the start point to the end point. If the program tries to move from the starting point along a line to another point in the path (otherpoint, abbreviated as OP ), the estimated distance from SP to EP obtained in this scheme is: the actual distance from SP to OP plus the est

We call Figure G a contest chart , when and only if it is a graph and its jhoira is a complete graph. In other words, directing the full graph to each edge will get a race chart.A competition chart with 4 vertices is displayed. Now, give you two of the graph P = (V,
