我感觉是跟底层的平台有关, 虽然两个加密解密算法都是在Java虚拟机上运行的, 一个是 Dalvik 一个是 JVM , 但是这两个虚拟机还是需要调用底层平台的 C 库 进行分析; Java服务器是 Linux 或者 WinSer x86平台 64位? Android的呢, arm 32位 ? 提出一个解决思路 : 你把每一步详细解析的数据, 每个位移, 每个计算结果都打印出来, 对比看看是哪里出现了问题; 参考博客 : http://blog.csdn.net/rj042/article/details/8196125 我没遇到过这种问题, 只是提出一个建议 ....

[韩曙亮]

又可能是 加密算法 对两种虚拟机底层不是完全兼容

[奋斗中的显摆]

猜测 有没有可能跟jdk有关系？

[rightorwrong]

是ace加解密 用到的库可能和jdk不兼容

[骷髅身]

用ace加解密的结果和用jdk加解密的结果不同，这个怎么解决

[路人贾]

你的服务器是 java的还是 php或是别的？ 用des 加密吧 或是 哈希，aes 会有一个 伪随机码的

[半夜回家]

你密钥有问题吧~~
