目前,我可以通过执行以下操作为本地数据库设置加密密钥：
if(![MyDemo_MyDemoDB databaseExists]){
SUPConnectionProfile* cp = [MyDemo_MyDemoDB
getConnectionProfile];
[cp setEncryptionKey:@"Yourkey"];
[MyDemo_MyDemoDB closeConnection];
}
因此,当我的用户成功登录时(通过提供SUPDataVault的正确密码),我收到以下错误：
ERROR sup_sqlite_db_ConnectionWrapperImpl.m:62 dynamicStatement: There is an exception file is encrypted or is not a database 2011-12-21 13:32:05.112 MyDemo10389:11603 MBODebugLogger: SUPPersistenceException SUPPersistenceException from find: -- sup_sqlite_db_StatementWrapperImpl: There is an exception null value for sqlite3_stmt 2011-12-21 13:32:05.225 MyDemo10389:11603 *** Terminating app due to uncaught exception 'SUPPersistenceException',reason: 'SUPPersistenceException from find: -- sup_sqlite_db_StatementWrapperImpl: There is an exception null value for sqlite3_stmt'
我认为正在发生的是,虽然数据库已成功创建,但仍然是加密的.我该如何解密？
解决方法
实际上这很简单,我每次开始会话时都需要这样做：
SUPConnectionProfile* cp = [MyDemo_MyDemoDB
getConnectionProfile];
[cp setEncryptionKey:@"Yourkey"];
