1. 安装crypto-js

cnpm install crypto-js --save

1. 封装一个des.js

ECB模式

import cryptoJs from 'crypto-js'

// DES加密

export const encryptDes = (message, key) => {

  var keyHex = cryptoJs.enc.Utf8.parse(key)

  var option = { mode: cryptoJs.mode.ECB, padding: cryptoJs.pad.Pkcs7 }

  var encrypted = cryptoJs.DES.encrypt(message, keyHex, option)

  return encrypted.ciphertext.toString()

}

// DES解密

export const decryptDes = (message, key) => {

  var keyHex = cryptoJs.enc.Utf8.parse(key)

  var decrypted = cryptoJs.DES.decrypt(

    {

      ciphertext: cryptoJs.enc.Hex.parse(message)

    },

    keyHex,

    {

      mode: cryptoJs.mode.ECB,

      padding: cryptoJs.pad.Pkcs7

    }

  )

  return decrypted.toString(cryptoJs.enc.Utf8)

}

CBC模式

import cryptoJs from 'crypto-js'

// DES加密

export const encryptDes = (message, key, iv) => {

  var keyHex = cryptoJs.enc.Utf8.parse(key)

  var ivHex = cryptoJs.enc.Utf8.parse(iv)

  var option = { iv: ivHex, mode: cryptoJs.mode.CBC, padding: cryptoJs.pad.Pkcs7 }

  var encrypted = cryptoJs.DES.encrypt(message, keyHex, option)

  return encrypted.ciphertext.toString()

}

// DES解密

export const decryptDes = (message, key, iv) => {

  var keyHex = cryptoJs.enc.Utf8.parse(key)

  var ivHex = cryptoJs.enc.Utf8.parse(iv)

  var decrypted = cryptoJs.DES.decrypt(

    {

      ciphertext: cryptoJs.enc.Hex.parse(message)

    },

    keyHex,

    {

      iv: ivHex,

      mode: cryptoJs.mode.CBC,

      padding: cryptoJs.pad.Pkcs7

    }

  )

  return decrypted.toString(cryptoJs.enc.Utf8)

}

1. 使用des.js

ECB模式

import { encryptDes, decryptDes } from './des.js'  // 引用路径根据自己的文件结构而定

encryptDes('要加密的数据', '加密的key')

decryptDes('要解密的数据', '解密的key')

CBC模式

import { encryptDes, decryptDes } from './des.js'  // 引用路径根据自己的文件结构而定

encryptDes('要加密的数据', '加密的key', '加密的iv')

decryptDes('要解密的数据', '解密的key', '解密的iv')
