该方法将返回一个数组，其中包含所有支持的密码算法的名称。crypto 包中有大量我们可以使用的密码算法列表。但最常用的密码算法是“AES – 高级加密标准”。crypto.getCiphers()
crypto.getCiphers()
因为它返回所有密码算法的列表。它不需要任何输入。
创建一个具有名称的文件 -getCipher.js并复制以下代码片段。创建文件后，使用以下命令运行此代码，如下例所示 -
node getCipher.js
获取密码.js
// 获取所有密码算法的节点演示程序
// 导入加密模块
const crypto = require('crypto');
// 调用 getCiphers() 方法
const cipher = crypto.getCiphers();
// 打印所有算法的列表
console.log("所有密码算法列表如下： ", cipher);输出结果C:\home\node>> node getCipher.js 所有密码算法列表如下： [ 'aes-128-cbc', 'aes-128-cbc-hmac-sha1', 'aes-128-cbc-hmac-sha256', 'aes-128-ccm', 'aes-128-cfb', 'aes-128-cfb1', 'aes-128-cfb8', 'aes-128-ctr', 'aes-128-ecb', 'aes-128-gcm', 'aes-128-ocb', 'aes-128-ofb', 'aes-128-xts', 'aes-192-cbc', 'aes-192-ccm', 'aes-192-cfb', 'aes-192-cfb1', 'aes-192-cfb8', 'aes-192-ctr', 'aes-192-ecb', 'aes-192-gcm', 'aes-192-ocb', 'aes-192-ofb', 'aes-256-cbc', 'aes-256-cbc-hmac-sha1', 'aes-256-cbc-hmac-sha256', 'aes-256-ccm', 'aes-256-cfb', 'aes-256-cfb1', 'aes-256-cfb8', 'aes-256-ctr', 'aes-256-ecb', 'aes-256-gcm', 'aes-256-ocb', 'aes-256-ofb', 'aes-256-xts', 'aes128', 'aes128-wrap', 'aes192', 'aes192-wrap', 'aes256', 'aes256-wrap', 'aria-128-cbc', 'aria-128-ccm', 'aria-128-cfb', 'aria-128-cfb1', 'aria-128-cfb8', 'aria-128-ctr', 'aria-128-ecb', 'aria-128-gcm', 'aria-128-ofb', 'aria-192-cbc', 'aria-192-ccm', 'aria-192-cfb', 'aria-192-cfb1', 'aria-192-cfb8', 'aria-192-ctr', 'aria-192-ecb', 'aria-192-gcm', 'aria-192-ofb', 'aria-256-cbc', 'aria-256-ccm', 'aria-256-cfb', 'aria-256-cfb1', 'aria-256-cfb8', 'aria-256-ctr', 'aria-256-ecb', 'aria-256-gcm', 'aria-256-ofb', 'aria128', 'aria192', 'aria256', 'bf', 'bf-cbc', 'bf-cfb', 'bf-ecb', 'bf-ofb', 'blowfish', 'camellia-128-cbc', 'camellia-128-cfb', 'camellia-128-cfb1', 'camellia-128-cfb8', 'camellia-128-ctr', 'camellia-128-ecb', 'camellia-128-ofb', 'camellia-192-cbc', 'camellia-192-cfb', 'camellia-192-cfb1', 'camellia-192-cfb8', 'camellia-192-ctr', 'camellia-192-ecb', 'camellia-192-ofb', 'camellia-256-cbc', 'camellia-256-cfb', 'camellia-256-cfb1', 'camellia-256-cfb8', 'camellia-256-ctr', 'camellia-256-ecb', 'camellia-256-ofb', 'camellia128', ... 70 more items ]
