对于这个应用程序,我有一个使用受密码保护的 sqlcipher 的数据库。

我有一个活动允许我使用以下代码更改密码:

SQLiteDatabase database = SQLiteDatabase.openDatabase(getDatabasePath("db").getPath() , oldPass, null,0) ;
database.rawExecSQL("PRAGMA rekey = '"+newPass+"';");
database.close();

执行前一段代码后,应用程序恢复正常操作,同时尝试再次访问数据库,我得到:

10-21 16:40:28.961  26635-26635/com.example            E/Database: CREATE TABLE android_metadata failed
10-21 16:40:28.981  26635-26635/com.example            E/Database: Failed to setLocale() when constructing, closing the database
        net.sqlcipher.database.SQLiteException: file is encrypted or is not a database

        at net.sqlcipher.database.SQLiteDatabase.openOrCreateDatabase(SQLiteDatabase.java:943)
        at net.sqlcipher.database.SQLiteOpenHelper.getWritableDatabase(SQLiteOpenHelper.java:107)

其次是:

Caused by: net.sqlcipher.database.SQLiteException: file is encrypted or is not a database
    at net.sqlcipher.database.SQLiteDatabase.native_setLocale(Native Method)
    at net.sqlcipher.database.SQLiteDatabase.setLocale(SQLiteDatabase.java:2101)

    at net.sqlcipher.database.SQLiteDatabase.openOrCreateDatabase(SQLiteDatabase.java:943)
    at net.sqlcipher.database.SQLiteOpenHelper.getWritableDatabase(SQLiteOpenHelper.java:107)

有人对这里发生的事情有任何提示或想法吗?我可能正在更改密码错误,或者其他什么。

我真的很感激任何帮助。

SQLCipher API 文档

Rekey 不能用于加密启动时未加密的数据库。如果您的用户从空密码更改为非空密码,它将以您描述的方式失败。他们在此处记录了如何加密以前未加密的数据库。

发行

database.rawExecSQL("BEGIN IMMEDIATE TRANSACTION;");

在...之前

database.rawExecSQL("PRAGMA rekey = '"+newPass+"';");

应确保在此期间没有其他数据库连接能够写入数据库。

请确认您在恢复您的申请时使用的是新密码,因为它与调用有关SQLiteOpenHelper.getWritableDatabase(…)
