javascript - JavaScript中的SecureRandom？(SecureRandom in JavaScript?)

Question

JavaScript中是否有类似SecureRandom.hex()的（ruby）函数为我生成随机哈希？

Answer 1

There is no such helper function in JS.

(JS中没有此类帮助程序功能。)

You can generates a fairly random hash using:

(您可以使用以下方法生成相当随机的哈希：)

function hex(n){
 n = n || 16;
 var result = '';
 while (n--){
  result += Math.floor(Math.random()*16).toString(16).toUpperCase();
 }
 return result;
}

You can modify it to form a guid:

(您可以对其进行修改以形成引导：)

function generateGuid(){
 var result = '', n=0;
 while (n<32){
  result += (~[8,12,16,20].indexOf(n++) ? '-': '') +    
            Math.floor(Math.random()*16).toString(16).toUpperCase();
 }
 return result;
}
