如何开始使用SQLCipher for android？ [英] How to get started with SQLCipher for android?
问题描述
我需要使用SQLCipher for android ...我已经使我们的应用程序使用SQLite，只想将其转换为SQLCipher。
I need to use SQLCipher for android...i've already made my app using SQLite and want to just convert it to SQLCipher.
问题是，我不知道SQLCipher。
The problem is, I know nothing about SQLCipher.
我已经阅读了这个链接： http://sqlcipher.net/sqlcipher-for-android/
I have read about it in this link: http://sqlcipher.net/sqlcipher-for-android/
但我不太清楚，还是。
我想知道你是否可以为安卓教程提供一些基本的sqlcipher，其中一切都是从绝对基础的一个简单的方法教。
But i'm not too clear, still. I was wondering if you could provide some basic sqlcipher for android tutorials, where everything is taught in an easy way from the absolute basics.
谢谢！ p>
Thanks!
推荐答案
要正确使用SQL Cipher for Android，您必须使用外部库，并更改一些与您的数据库交互的代码。
To properly use SQL Cipher for Android you must use external libraries and change some of the code which interacts with your DB.
-
这些必须首先添加到您的项目中（在libs文件夹中。）请参阅这里获取这些： http://sqlcipher.net/sqlcipher-for-android/
其次，您需要将icudt4dl.zip文件添加到assets文件夹，此Zip随SQL Cipher库一起提供。
Secondly you need to add the icudt4dl.zip file to your assets folder, this Zip comes with the SQL Cipher libraries.
右键单击您的项目，转到属性然后Java构建路径，然后包括库，如commons-codec.jar，guava-r09.jar，sqlcipher.jar。一旦这样做，做一个清洁。
Right click your project, go to properties then Java build path then include libraries such as commons-codec.jar, guava-r09.jar, sqlcipher.jar. Once this is done, do a build clean.
然后在你的应用程序，而不是导入android.database.sqlite，你将导入import net.sqlcipher。数据库
Then within your App, instead of importing android.database.sqlite, you will import import net.sqlcipher.database
更改与数据库交互的任何代码，例如：
Change any code which interacts with the DB, example:
SQLiteDatabase.loadLibs ）;
SQLiteDatabase.loadLibs(context);
字符串dbPath = this.getDatabasePath（dbname.db）。getPath（）;
String dbPath = this.getDatabasePath("dbname.db").getPath();
SQLiteDatabase db = SQLiteDatabase.openOrCreateDatabase（dbPath，dbPassword，null）;
SQLiteDatabase db = SQLiteDatabase.openOrCreateDatabase(dbPath,"dbPassword", null);
验证数据库是否加密，在Eclipse中转到DDMS透视图，文件浏览器选项卡，导航到数据/数据/，单击.db文件并选择获取设备文件，将其保存到您的桌面，并使用文本编辑器打开它。查找您已插入到数据库中的纯文本值，如果您仍然可以阅读它们，则出现错误。
Verify that the database is encrypted, go to DDMS perspective in Eclipse, click the file explorer tab, navigate to data/data/, click on the .db file and select get device file, save it to your desktop and open it with a text editor. Look for the plain text values you have been inserting into your database, if you can still read them, something has gone wrong.
在实现SQL Cipher之前检查一些SQLite教程也是一个好主意。这里提到一个好的：
It might also be a good idea to check out some SQLite tutorials before implementing SQL Cipher. A good one is mentioned here: Android sqlite database - where do i start as the tutorial has gone for notepad?
更新
这个答案现在已经过时，Eclipse几乎已不适用于Android开发。我最近不得不在Android Studio + Android 5 + 6上使用SQLCipher构建一个应用程序，这些是我遵循的步骤。
This answer is outdated now and Eclipse is practically deprecated for Android Development. I recently had to build an app using SQLCipher on Android Studio for Android 5 + 6 and these are the steps I followed.
在Android Studio中，可以包括SQLCipher在你的构建文件中的依赖。在构建gradle中更新您的依赖关系，以包括以下行：
In Android Studio, you can include SQLCipher as a dependency in your build file. Update your dependencies in build gradle to include the following line:
dependencies{
compile 'net.zetetic:android-database-sqlcipher:3.5.4@aar'
}
版本：
https://mvnrepository.com/artifact/ net.zetetic / android-database-sqlcipher
我的应用程序不会构建，除非我删除lib文件夹和资产文件夹中的SQLCipher文件，之后它按预期工作。一旦你做了这些更改，运行一个build / clean并检查它是否工作。
My App wouldn't build unless I removed the SQLCipher files in the lib folder and the asset folder, but after that it worked as expected. Once you made these changes, run a build/clean and check if it works.
上述与更改代码相同的步骤仍然有效。
