Android上的基本加密 [英] Basic encryption on Android

问题描述

我已经看到此处的示例。一切都很好，我明白了，但是它依赖于提供商的bounceycastle库。如果我可以帮助我，我不想捆绑任何额外的第三方库与我的应用程序。我不需要Fort Knox风格的安全，只是一些基本的对称加密通过电线传输。如何在Android上使用第三方库进行基本加密？

I have seen the example here. All well and good and I understand it, however it relies on the bounceycastle library for the provider. I don't want to bundle any additional third party libraries with my app if I can help it. I don't need fort knox style security, just some basic symmetric encryption for transmitting over the wire. How can I do basic encryption on Android with out third party libraries?

谢谢

推荐答案

Well BouncyCastle包含在Android中，您可以看到您是否尝试包含它将获得： D / dalvikvm（9268）：DexOpt：不验证'Lorg / bouncycastle / x509 / extension / SubjectKeyIdentifierStructure;'：多个定义等等。

然而，并不是所有的算法都被实现 - 你会得到一个NoSuchAlgorithmException。
在Android 2.2中，我发现这些被实现：

However, not all algorithms are implemented - you would get an NoSuchAlgorithmException. In Android 2.2 I found these to be implemented:

PBEWITHSHAAND128BITAES-CBC-BC
PBEWITHSHAAND3-KEYTRIPLEDES-CBC
1.2.840.113549.1.1.7
PBEWITHSHA256AND256BITAES-CBC-BC
