1.下载

git clone https://github.com/devbean/QtCipherSqlitePlugin.git

2.编译CipherSqlite插件

使用qt打开QtCipherSqlitePlugin项目，并构建插件

3.将构建的插件复制到安装目录

4.使用DB Browser (SQLCipher)创建数据库并加密

5.qt使用CipherSqlite插件连接加密数据库

cpp 复制代码

	QString dbFilePath = QCoreApplication::applicationDirPath() + "/db/test.db";
    QSqlDatabase dbconn = QSqlDatabase::addDatabase("SQLITECIPHER");
    dbconn.setDatabaseName(dbFilePath);

    dbconn.setPassword("123");
    //如果在debug窗口输出dbconn.driver():  SQLiteCipherDriver(0x2360f83aa30)，证明插件导入成功
    qDebug() << "dbconn.driver(): " << dbconn.driver();
    dbconn.setConnectOptions("QSQLITE_USE_CIPHER=sqlcipher; SQLCIPHER_LEGACY=4; SQLCIPHER_LEGACY_PAGE_SIZE=4096");

    // 打开数据库连接
    if (dbconn.open()) {
        qDebug() << "Success to open the database";
    } else {
        qDebug() << "Failed to open the database:" << dbconn.lastError().text();
    }
