为了生成更加可靠的随机数,微软在System.Security.Cryptography命名空间下提供一个名为system.Security.Cryptography.RNGCryptoServiceProvider的类,它采用系统当前的硬件信息.进程信息.线程信息.系统启动时间和当前精确时间作为填充因子,通过更好的算法生成高质量的随机数,生成强随机字符串的方法如下所示: using System.Security.Cryptography; sealed class RNGCryptoRand…

function a(a) { var d, e, b = "abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789", c = ""; for (d = 0; a > d; d += 1) e = Math.random() * b.length, e = Math.floor(e), c += b.charAt(e); return c }…
