RSA在Android上加密和解密字符串 [英] RSA Encrypt and Decrypt Strings on Android
问题描述
自从几周以来我正在阅读页面和页面,但是找不到解决方案。
我想只到:
I'm reading pages and pages since weeks but I cannot find a solution. I want "only" to:
- 使我自己的公钥和私钥加密和解密我的PHP网站和Android应用程式(例如 http://www.example-code.com/android/rsa_generateKey .asp ,但是如何存储和使用生成的密钥?)
- 在我的应用程序中加密字符串
- 将字符串解密我的网站
- 在我的网站上加密字符串
- 从我的应用程序解密字符串
- Make my own public and private keys to encrypt and decrypt strings between my PHP website and Android application (like on http://www.example-code.com/android/rsa_generateKey.asp but how can I store and use the generated keys?)
- Encrypt a string on my application
- Decrypt the string from my website
- Encrypt a string on my website
- Decrypt the string from my application
我刚刚发现了一个简单的这个工作的类( http://www.example-code.com/android/rsa_encryptStrings.asp )但是它不是免费的,并且使其在PHP上工作我应该安装一个PHP扩展名,但是我不能在我的网络托管。
I've just found a class that does simply this job ( http://www.example-code.com/android/rsa_encryptStrings.asp ) but it is not free, and to make it work on PHP I should install a PHP extension but I can't on my web hosting.
有什么类似的东西吗?我正在学习很多,但我不知道为什么我不明白如何以不同的方式做到这一点。
Is there something similar? I'm studying a lot but I don't know why I don't understand how to do it in different ways.
可能类似于
可以帮助,但它不是完整的源代码。

请给我一些真正的工作示例。
Please give me some real working examples.
