This article describes the JS password generation and strength detection methods. Share to everyone for your reference, specific as follows:
1. Generate Strong passwords
Screenshot below:
The relevant code is as follows:
function Getpwd (n)
{
var s = ';
while (n--)
s + + string.fromcharcode (+ Math.floor (Math.random () * (126-33)))
document.getElementById (' Txt1 '). Value = S;
}
2. Calculate Password cracking time

First we need to know if the program has a memory leak, and then locate which line of code is leaking memory so that it can be repaired.
The simplest method of course is the use of professional testing tools, more famous such as Boundscheck, the function is very strong, I believe that people do C + + development can not be separated from it. In addition, you do not use any of the tools, but to implement the memory leak monitoring, in the following two cases:

Collision Detection on3DThe game is crucial. A good collision detection requires that the characters can be smoothly moved in the scene, and the steps within a certain height can automatically go up, while the high steps block people, when a slope with a small slope can be up, the slope is too large to block people, in the case of various forward direction is blocked, we should try to let the characters sli

With the development of wireless technology and network technology, wireless networks are becoming a hot spot in the market. However, with the improvement of hacker technology, wireless LAN (WLAN) is under more and more threats. Wireless networks are not only attacked based on the traditional wired network's TCP/IP architecture, but may also be threatened by security issues based on the IEEE 802.11 standard. In order to better detect and defend against these potential threats, th
For the vulnerabilities in the intrusion detection system, let's take a look at hacker intrusion techniques. Once the network intrusion detection system is installed, the network intrusion detection system will analyze the online hacker attack events for you, and you can use the counterattack function of this intrusion detect
