在Android基础的加密 [英] Basic encryption on Android
问题描述
我见过的例子这里。一切都很好，我理解它，但是它依赖于供应商的bounceycastle库。我不想捆绑任何额外的第三方库与我的应用程序，如果我能帮助它。我不需要诺克斯风格的堡垒安全性，通过导线传输只是一些基本的对称加密。我该怎么做基本的加密Android上使用了第三方库？
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?
感谢
推荐答案
那么BouncyCastle的是包含在Android中，你可以看到，如果你会尝试把它列入你会得到： D / dalvikvm（9268 ）：DexOpt：未验证Lorg / BouncyCastle的/ X509 /推广/ SubjectKeyIdentifierStructure;'：多重定义等
Well BouncyCastle is included in Android, as you can see if you would try to include it you would get: D/dalvikvm( 9268): DexOpt: not verifying 'Lorg/bouncycastle/x509/extension/SubjectKeyIdentifierStructure;': multiple definitions and so on.
然而，并非所有的算法中实现 - 你会得到一个抛出：NoSuchAlgorithmException。 在Android 2.2的我发现这些即将实施：
However, not all algorithms are implemented - you would get an NoSuchAlgorithmException. In Android 2.2 I found these to be implemented:
