如何修改加密的app.config文件的密钥和值？

Question

I am very new on c#/Visual Studio and I'm having difficulty on running my test methods. It requires us to connect to a database server resulting of getting always a failed result since we can't connect to the database.

We tried to modify the connection string to include our working credentials so that we can connect to the database server but the app.config file was encrypted.

Please see below screenshot of example encrypted line. How can we modify that?

Answer 1

As I see it I think the connectionstring is encrypted outside the project and pasted here. I am saying this because IMO encrypting just the connection string value and keeping the key in plain text is not possible from within the project. It is possible to encrypt the entire section within a config file.

Check the method which is using this connectionstring. I believe The method might be using some form of decryption. Use that to decrypt the string, change the values as required, encrypt it again and paste it in the above location.

You can also edit your question to include the method which is using the connectionstring so that I can analyse it and give you a better solution.

Hope this helps.
