AES128加密失败问题？

Question

import cryptoFramework from '@ohos.security.cryptoFramework';
import { BusinessError } from '@kit.BasicServicesKit';
import { util } from '@kit.ArkTS';


function stringToArray(str: string): Uint8Array {
  let textEncoder = new util.TextEncoder();
  return textEncoder.encodeInto(str);
}

@Entry
@Component
