sqlcipher - 更改数据库密码失败

【问题标题】：sqlcipher - Changing DB password failingsqlcipher - 更改数据库密码失败
【发布时间】：2013-10-21 15:57:23
【问题描述】：

对于这个应用程序，我有一个使用密码保护的 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();

在执行前一段代码后，应用程序恢复正常运行，同时尝试再次访问数据库：

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.native_setLocale(Native Method)
        at net.sqlcipher.database.SQLiteDatabase.setLocale(SQLiteDatabase.java:2101)
        at net.sqlcipher.database.SQLiteDatabase.<init>(SQLiteDatabase.java:1967)
        at net.sqlcipher.database.SQLiteDatabase.openDatabase(SQLiteDatabase.java:900)
        at net.sqlcipher.database.SQLiteDatabase.openOrCreateDatabase(SQLiteDatabase.java:943)
        at net.sqlcipher.database.SQLiteOpenHelper.getWritableDatabase(SQLiteOpenHelper.java:107)

接着是：

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。

非常感谢任何帮助。

编辑2：

database.rawExecSQL("BEGIN IMMEDIATE TRANSACTION;");
database.rawExecSQL("PRAGMA rekey = '"+newPass+"';");
database.close();

紧随其后

getWritableDatabase(newPass);

Edit3 - 解决方案：

DB 文件在安装时使用空字符串加密。

【问题讨论】：

  • 虽然您将 oldPass 传递给 openDatabase()，但请尝试在 PRAGMA REKEY 之前调用 PRAGMA KEY（再次使用 oldPass）。
  • 你好 NuSkooler。以前这样做过，但也没有用。

标签： android sqlite sqlcipher


【解决方案1】：

SQLCipher API Documentation

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。他们记录了如何加密以前未加密的数据库here。

【讨论】：

  • 这实际上是一个好点。原始数据库加密文件使用空密码。完全忘记了这一点，所以感谢您指出这一点。
【解决方案2】： 
SQLiteDatabase.rawExecSQL("PRAGMA key = 'old_password';");
SQLiteDatabase.rawExecSQL("PRAGMA rekey = 'new_password';");

【讨论】：

    【解决方案3】：

    发行

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

    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。

    【讨论】：

    • 您尝试重新加密的加密数据库是您使用相同版本的 SQLCipher 创建的数据库吗？如果您针对 1.x 数据库使用 SQLCipher 2.0，则默认情况下 SQLCipher 2 无法在 1.1.x 版数据库上运行。因此，为了提供与 SQLCipher 1.1.x 的向后兼容性，PRAGMA cipher_use_hmac 可用于禁用特定数据库上的 HMAC 功能。 [链接]sqlcipher.net/sqlcipher-api/#cipher_use_hmac
    • 是同一版本的 SQLCipher。问题是原始数据库文件正在使用空密码进行加密。感谢您的评论
    • 如何停止交易..更改密码后..如果我尝试在数据库中插入一些数据...我收到错误cannot start a transaction within a transaction: BEGIN EXCLUSIVE; 但如果我不使用@987654326 @我在插入数据时没有收到任何错误..
    【解决方案4】：

    请确认您在恢复申请时使用的是新密码，因为它与SQLiteOpenHelper.getWritableDatabase(…) 中的呼叫有关。

    【讨论】：

    • 是的，我确定我使用的是新密码
