    對於這個程序，我有一個使用sqlcipher的密碼保護的數據庫。sqlcipher - 更改數據庫密碼失敗

    我有一個活動，讓我用下面的代碼更改密碼：

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

    執行代碼的前一位後，應用程序的同時試圖再次我得到訪問數據庫恢復正常運行：

    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：

    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)

    任何甲肝e有關這裏發生的事情的任何提示或想法？我可能會改變密碼錯誤，或其他。

    我真的很感激任何幫助。

    編輯1：執行日誌修改通，並試圖再次打開數據庫文件：

    的DB文件是在安裝時被加密，一個空字符串。

    雖然您將oldPass傳遞給openDatabase（），但在PRAGMA REKEY之前，請嘗試調用PRAGMA KEY（再次使用oldPass）。 – NuSkooler

    Hello NuSkooler。之前做過，也沒有工作。 – SysHex

    請確認您在恢復應用程序時使用新密碼，因爲它與SQLiteOpenHelper.getWritableDatabase(…)中的呼叫有關。

    是的，我確定我正在使用新密碼 – SysHex

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

    之前

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

    發行應確保沒有其他的數據庫連接將能夠寫在其間數據庫。

    感謝您的回答。不幸的是它沒有奏效。 – SysHex

    加密的數據庫是否正在嘗試重新生成密鑰，是否使用相同版本的SQLCipher創建了一個？如果您使用SQLCipher 2.0處理1.x數據庫，則默認情況下，SQLCipher 2無法在版本1.1.x數據庫上運行。因此，爲了提供與SQLCipher 1.1.x的後向兼容性，可以使用PRAGMA cipher_use_hmac來禁用特定數據庫上的HMAC功能。 [鏈接] http://sqlcipher.net/sqlcipher-api/#cipher_use_hmac – PositiveLogic

    +0

    是SQLCipher的相同版本。問題在於原始數據庫文件正在使用空密碼進行加密。感謝您的評論 – SysHex

    SQLCipher API Documentation

    重新建立密鑰不能被用於加密未加密啓動數據庫。如果您的用戶正在從空密碼更改爲非空密碼，則它會以您描述的方式失敗。他們記錄瞭如何加密以前未加密的數據庫here。

    ，這實際上是一個很好的觀點。原始的DB加密文件使用空密碼。完全忘了這一點，所以謝謝你指出。 – SysHex
