求大神解答几个问题

[shenyunhuan]

1 SIGN_FRONT_DEBUG SIGN_END_DEBUG 是哪几位，怎么来的，我debug模式得到了SIGN_END_DEBUG的值但是SIGN_FRONT_DEBUG 怎么还是和你的一样，debug签名不一样啊
2 native解密报错
3 不支持中文
4 服务器怎么解密呢

[dfqin]

1. SIGN_FRONT_DEBUG这些本来就是写死的常量，用来判断是不是自己的签名。
   2.多放些log出来吧，我这边无法重现。
   3.应该不可能，加密是针对byte数组的。
   4.demo中以实现

[shenyunhuan]

你试试纯中文
2 ：byte[] oriData = SecureUtil.decryptData(deData); 这行代码报错
JNI DETECTED ERROR IN APPLICATION: negative jsize: -50

我看了一下，可能是只有arm64-v8a 的so文件 原因
