Node.js crypto.getHashes()用法及代码示例

crypto.getHashes()方法是加密模块的内置应用程序编程接口，用于显示数组中所有受支持的哈希算法的名称。

用法:

crypto.getHashes()

参数：此方法不接受任何参数。

返回值：它返回所有受支持的哈希算法的名称。

以下示例说明了Node.js中crypto.getHashes()方法的使用：

例：

// Node.js program to demonstrate the  
// crypto.getHashes() method 
  
// Including crypto module 
const crypto = require('crypto'); 
  
// Calling getHashes method 
const hash = crypto.getHashes(); 
  
// Prints all the supported hash algorithms 
console.log("The list of all the hash "
        + "algorithms are:", hash);

输出：

The list of all the hash algorithms are: [ 'RSA-MD4',
