Node.js | crypto.getCiphers() 方法

crypto.getCiphers() 方法是 Node.js 的内置模块 crypto 中的一部分，用于返回一个数组，其中包含支持的密码算法名的字符串。这些密码算法名可以用于 createCipher() 和 createDecipher() 方法。

语法

以下是 crypto.getCiphers() 方法的语法：

crypto.getCiphers()

返回值

crypto.getCiphers() 返回一个字符串数组，其中包含支持的密码算法名。

示例

以下代码示例演示如何使用 crypto.getCiphers() 方法：

const crypto = require('crypto');

const ciphers = crypto.getCiphers();

console.log('支持的密码算法：', ciphers);

运行上述代码输出结果如下：
