it's my first Question, so please don't be harsh if you're seeing any mistakes.
I'm creating an embedded HSQLDB via a Client.
con = DriverManager.getConnection("jdbc:hsqldb:file:"
+ dataBaseName
+ ";crypt_key=604a6105889da65326bf35790a923932;crypt_type=blowfish;shutdown=true","sa", "");
It's encrypted with Blowfish. I only defined the Key. Now i want to decrypt the .script File with Notepad++ Extensions but it asks for an IV-Key and the Salt. I haven't defined these Arguments but i need them.
Any Suggestions?
Thanks in Advance
You cannot do it directly.
Connect to the database via any client. Then use the command below for the name and location for saving the .script file in non-encrypted format.
SCRIPT 'path/filename'

I'm working with a company trying to setup a new database system as their old database software has gone out of business. All the data is in a .fb file that is encrypted (You used to have to get backups 'unlocked' before they would let you use them).
I've managed to get a copy of the database (I think it's unencrypted as I copied it while the database was open and then changed the copied files permissions using terminal).
The problem is that it's a .fb file and I can't find a way to 'open' it to browse the data...
Any Ideas?
Generally speaking, data stored in relational databases aren't just stored as ascii csv files. So you won't be able to just open up a .fb file in a text editor and grab the data.
If you're still able to query the database, you will need to have the frontbase server generate a dump of the data into a flat file.
See the frontbase documentation for backup and restore. Specifically 4.9.1. Exporting Schema and Content Data:
WRITE ALL OUTPUT('<output-directory>' [,'YES']);
I used Navicat Premium to create the database file and selected encrypted to put a password. Now when I try accessing the database in my vb.net program I get an error saying...
file is encrypted or is not a database
"Data Source=\\10.10.10.10\Folder\database.db;Password=pwd;Version=3;", True
The above is my connection string (please ignore the network path =) ). Anyway, I can get through opening the connection but when reading data I get the error. I tried creating another database that doesn't have a password and it worked fine. I even copy pasted the password I have in code to navicat to make sure i typed it correctly.
I am trying to set a connection between Dreamweaver and Sql server database,
i am using the wizard under Dreamweaver CS3
the wizard creates a file named connections and inside that file i have
<%
' FileName="Connection_ado_conn_string.htm"
' Type="ADO"
' DesigntimeType="ADO"
' HTTP="false"
' Catalog=""
' Schema=""
Dim MM_Q_S_Conn_STRING
MM_Q_S_Conn_STRING = "Driver={SQL Server};ServeR=\SQL08R2T_INST4;Database=XTEST;Uid= TDWEAVER;Pwd=tdweaver;"
%>
all is working fine and i can access the database and add/delete/update records
The administrator is asking to apply encryption to the password and send him the way the encryption is performed
Can i add encryption to the password inside the Connection String? or maybe add encryption type ?
Any help please
My first question would be: Does the driver encrypt the connection to the database? If not, then what's the point of encrypting the password when the first connection publishes it as plain text on the local network?
The next question: Why can anyone read the file? If only the process can read the file, what additional security does encrypting the password provide?
For me, this feels like security by obscurity which is a valid security layer if you have covered all the other bases. If you didn't, then it's just a waste of time.
What is the process to take a backup of all the connection-details (viz. host,port,sid,etc.) in 'oracle sqldeveloper' software.
How can we import these connection details to some other machine ?
The 'oracle sqldeveloper' stores all the connection details in an xml file ie. connections.xml.
If you want to have a backup for the connection details, you will have to navigate to
In windows XP
C:\Documents and Settings\<YourUserName>\Application Data\SQL Developer\systemX.X.X.X.X\o.jdeveloper.db.connection.X.X.X.X.X.X.X\
In Windows 7
C:\Users\<YourUserName>\AppData\Roaming\SQL Developer\systemX.X.X.X.X\o.jdeveloper.db.connection.X.X.X.X.X.X.X\
and take a backup of connections.xml .
Later, if you need to use the same connections on some other machine, you may simply copy the <Reference ...> tags for respective connections.
From Sql developer you can export the connections and then easily import them
Right click connection.
Select Export
Browse to provide it a xml file path to export connection. Select Ok.
Click Import in connections similarly to export.
Select the xml file and all your connections should be imported.
Note : If you are using Connection type as TNS and providing alais then you will have to export tnsnames.ora file separately. Then provide it to sql developer using
Tools -> Preferences -> Database -> Advanced -> Tnsnames directory
Step 1. Right click on connections and choose the Export Connections.
Step 2. In the File Name sections provide the name of connections file you want to save at your local computer. and click OK. your connections xml file will be saved at your provided location.
NOTE: To import the connections in your sql developer choose the Import Connections..
This link Migrating Oracle SQL Developer Connections with Passwords provides a much better way to do it.
Do to unfortunate circumstances, a new Windows profile was set up for me so I lost all my database connections. Fortunately, my old profile folder had been saved under a different name before the new one was set up.
I was able to use the information from two of the above answers and this post to import my connections with passwords.
Steps:
When in SQL Developer, I right-clicked on "Connections" and chose "Import Connections..." as per the answer by #AniketThakur.
I selected the connections.xml file from my old profile. I found it using the answer by #Satyendra.
The Import dialog gives the choice of discarding passwords or entering the key that was used to encrypt them. This is where this post helped. I found the key by searching under the \systemX.X.X.X.X\ folder for a file named product-preferences.xml. Inside that file I searched for an element that looked like:
<value n="db.system.id" v="xxxxxxxxxxxxxxxxxxxxxxxxxxxxxx"/>
It appears the v value is the key that is needed to decrypt the passwords.
Note: The product-preferences.xml file was under:
\systemX.X.X.X.X\o.sqldeveloper\
(I am using Oracle SQL developer)
1) Go to View -> Connections
2) Right click on Connections -> Export Connections
3) Select the connections that you wish to export. Click Next.
3) Provide name to the file. Say export.xml (Sometimes you need to create a .xml file in some folder and then choose this file using Browse option)
4) If you wish to keep the passwords Saved in the xml file then choose "Encrypt all passwords with a key". Provide Encryption key. This will be used whenever you import the connections.
If passwords are not needed to be exported with the xml file then choose the other option "Remove all passwords from the exported connections"
5) Before clicking on Finish , see the destination of the xml file that is created.
To import the Connections, follow the similar procedure.

I have a stand-alone Windows Form app written in VB.NET that currently connects to a local Access DB (.mdb file) and consumes data from several of the tables. It never writes to nor modifies the DB. I'm trying to figure out how to secure this DB so the user has no access to it. I'm thinking the best way is to store the DB as an embedded resource within the project. However, I can't figure out how to make this work.
I've added the .mdb file to the project resources and set its properties to "Embedded Resource" and "Do not copy." But now how do I reference the DB to create the connection?
Before I used the connection string "Provider=Microsoft.Jet.OLEDB.4.0; Data Source=MyDatabase.mdb"
How do I write the connection string now with reference to an embedded resource?
"I'm thinking the best way is to store the DB as an embedded resource within the project."
This usually relates to old skool security, in the olden days DotNetNuke developers that used Access dBs as their backend actually renamed the .mdb to .resources as you cant download a resource file from the web.
"Would it be better to export the DB to xml or something like that and then use a stream reader as opposed to a database connection?"
No. You cant read an Access file from a stream And an XML dB has even less concurrency support than an Access Database.
If you really need to protect the data, then you've absolutely chosen the wrong data store.
#JohnBustos wrote "Store the DB remotely and have the program access it over the internet."
Please do not do this. If anything put it on a network share and restrict access. Then look at upgrading the access dB to SQL Server.
Yes, I have had the same problem and I converted the database into a XML or even a TXT file that is embedded. It works very fine !
Sorry, I never closed this out.
My solution was even simpler than those proposed. You can add the .mdb file to the project itself and not mess with the whole "Resource" business. Then set the file's Copy to Output property to "Do not copy". So the .mdb gets compiled into the app, but file itself is not available to the user.
