一、首先需下载大包: npm install crypto-js
二、然后下载ts版本包: npm install --save @types /crypto-js
三、示例代码:
import { Injectable } from "@angular/core" ;
import { DES, mode, pad, enc } from 'crypto-js' ;
@ Injectable ()
export class CryptUtil {
private keyHex : string ; //密钥
constructor () {
this .keyHex = enc.Utf8. parse ( 'LSand2019' );
}
/**
* DES加密
* @param {string} data 待加密字符串
* @description 用于对字符串加密
* @return {String} 加密后的字符串
*/
desEncrypt ( data : string ) : string {
let encrypted = DES. encrypt ( data , this .keyHex, {
mode: mode.ECB,
padding: pad.Pkcs7
})
return encrypted. toString ();
}
/**
* DES解密
* @param {String} data 待解密字符串
* @description 用于对加密串的解密
* @return {String} 解密后的字符串
*/
desDecrypt ( data : string ) : string {
let decrypted = DES. decrypt ( data , this .keyHex, {
mode: mode.ECB,
padding: pad.Pkcs7
})
return enc.Utf8. stringify (decrypted);
}
}
四、效果演示:
console. log ( "des加密123456结果:" , this .cryptUtil. desEncrypt ( '123456' ));
console. log ( "des解密olCPKgwi0rk=结果:" , this .cryptUtil. desDecrypt ( 'olCPKgwi0rk=' ));
