标题: [Bug]: 使用cryptoFramework加解密的时候，经常崩溃
【问题描述】
问题现象和发生的背景
HarmonyOS NEXT Developer Preview2模拟器：使用cryptoFramework加解密的时候，经常崩溃，同样的加解密代码，同样的数据，运行效果不同：大概率会失败、小概率会成功、经常会崩溃
同样的代码同样的数据，为什么会执行出不同的结果呢？

相关的代码，截图，日志信息
奔溃信息如下：

您好，我这边加解密传输测试暂时比较稳定，您可以试一下eftool中的加解密，或者整体传输加解密，如果不稳定的话烦请提交一个issue，eftool加解密详见eftool第二部分，efAxios整体传输加解密详见第三部分
