HarmonyOS 如何将md5变成字符串？

import { CryptoJS } from '@ohos/crypto-js'  
  
@Entry  
@Component  
struct Index {  
  build() {  
    Column() {  
      Text('xxxx').onClick(() => {  
        let md5:Object = CryptoJS.MD5(123456)  
        let str:string=md5.toString();  
        if (typeof (str) == 'string') {  
          console.info(str)  
        }  
      })  
    }.width('100%')  
    .height('100%')  
  }  
}
