安卓慢AES解密 [英] Android slow AES decryption

问题描述

参考:Android 加密/解密问题 (AES)

我正在构建一个 android 应用程序，它需要对一个非常大的包 (~50Mb) 进行 aes 解密，并且在 android 的内置 aes 解密机制中实现时它真的很慢(大约 5 分钟).

I am building an android app which requires aes decryption of a really large package (~50Mb) and it is really slow when implemented in android's inbuilt aes decryption mechanism (around 5 minutes).

基于 SO 中的上述帖子，我尝试使用 ndk 并尝试下载本机库 (openssl) 以用于此应用程序.但是，openssl for android 有很多文件，我不知道使用哪些文件来创建 .so 文件.

Based on the above posts in SO, I attempted to use ndk and tried to download native libraries (openssl) to use for this app. However, openssl for android has a really large number of files and I do not know which ones to use to create the .so file.

我对在 android 应用程序中使用 ndk 和本机代码非常缺乏经验，并且会发现有关如何使用 openssl 库进行 aes 解密的任何建议/示例代码非常有用.

I am quite inexperienced with the use of ndk and native code in android apps and would find any suggestions/sample code on how to use openssl library for aes decryption really useful.

推荐答案

尝试 SpongyCastle重新包装的 BouncyCastle 不会与 Android 发布的版本冲突.Android 系统上的版本很旧(如果您甚至发布了包含它的 Android 版本).

Try SpongyCastle its a repackaged BouncyCastle that wont conflict with the one released with Android. The one on Android systems is old (if you even have a release of Android that includes it).

这应该就是你所需要的.

This should be all you need.
