为数据库设置加密密钥（Sybase Unwired Platform）

目前，我可以通过执行以下操作来设置本地数据库的加密密钥：

 if(![MyDemo_MyDemoDB databaseExists]){
        SUPConnectionProfile* cp = [MyDemo_MyDemoDB
                                    getConnectionProfile];
        [cp setEncryptionKey:@"Yourkey"];
        [MyDemo_MyDemoDB closeConnection];
    }

所以，当我的用户成功登录时（通过为SUPDataVault提供正确的密码），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'

我认为正在发生的事情是，尽管数据库已经成功创建，但它仍然是加密的。 我如何解密它？

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"];
