1. 散列HASH
类对数据进行散列摘要的工具,使用示例:
const crypto = require('crypto');const hash = crypto.createHash('sha256');hash.update('123')console.log(hash.digest('hex'))
2. 散列消息身份验证码HMAC(Hashed Message Authentication Code)
类是创建HMAC摘要的工具。
const crypto = require('crypto');const hmac = crypto.createHmac('sha256','a secret');hmac.update('some data to hash')console.log(hmac.digest('hex'))
3. 加密解密
类用于加密数据,Decipher类用于解密数据。
AES加密示例:
const crypto = require('crypto');const cipher = crypto.createCipher('aes192', 'a password');let encrypted = cipher.update('some clear text data', 'utf8', 'hex');encrypted += cipher.final('hex');console.log(encrypted);
