AES 在密码学中又称 Rijndael 加密法。
首先下载大包

npm install crypto-js --save

然后下载ts版本的包

npm install --save @types/crypto-js

创建一个加密服务：crypto.service.ts

import { Injectable } from '@angular/core';
import { AES, enc, mode, pad } from 'crypto-js';@Injectable()
export class CryptoService {private key: string = 'xxxxxxxxxxxxxxxxxxxxxx';constructor() {}/*** AES加密*/encryptByEnAES(data: string): string {let Key = enc.Utf8.parse(this.key);let tmpAES = AES.encrypt(enc.Utf8.parse(data), Key, {mode: mode.ECB,padding: pad.Pkcs7});return tmpAES.toString();}/*** AES解密*/encryptByDeAES(data: string): string {let Key = enc.Utf8.parse(this.key);let tmpDeAES = AES.decrypt(data, Key, {mode: mode.ECB,padding: pad.Pkcs7});return tmpDeAES.toString(enc.Utf8);}
}
