Flexiprovider-如何使用格式化的密钥对加密解密

Flexiprovider-如何使用格式化的密钥对加密/解密

由于上述代码未解决的错误，因为我认为此flexiprovider与jdk-8不兼容，其中的错误位于“ KeyFactory kf =
KeyFactory.getInstance（“ ECIES”，“FlexiEC”）“行中，该行找不到我将其命名为曲线，然后更改并决定使用BouncyCastle提供程序进行EC加密（ECIES），并且它可以正常工作。但是我再次想到一个问题，就像我在使用的Flexiprovider中所看到的那样
（“ AES128_CBC”，“ HmacSHA1”，null，null）； 作为 IESParameterSpec 。但是对于
充气城堡 提供者，我找不到 IESParameterSpec 在 哪里
哪个使用AES128_CBC作为iesparameterspec，如果要在使用此d性提供程序时将iesparam更改为AES128_CBC，该怎么办？有人请在d性提供程序中解释有关此iesparam规范，我对此并不陌生。

这是我的信息代码：
