Protecting connection strings during dev

We need to protect connection strings during development. On servers we use DPAPI which works fine. DPAPI is not an option during dev since the connection strings will need to be decrypted on many machines.

Some of the user names/password used for dev are rather sensitive and we don't want them floating around. It's fine for all the devs to be able to decrypt them, just want to ensure that if someone else gets their hands on the dev config files that person can't decrypt the connection strings. Using all service accounts instead of sensitive username/password is not an option due to external constraints.

开发者_如何学JAVAMy first inclination is to use the RSA provider for encrypting and installing the cert on the dev machines.

So my questions are;

1) How do you approach this issue?

2) If you take the RSA approach is there more up-to-date documentation than this

Thanks

Well after more research we went with the RSA approach. Found some more updated documentation here. If you are going down this road make sure you read everything RSA related in that link. Below are the steps we used if anyone is interested...

--FIRST TIME ONLY

-create the key container, making it exportable

aspnet_regiis -pc "MyKeys" -exp

-add this section to config file

<configProtectedData>
  <providers>
    <add name="RsaProvider"
         type="System.Configuration.RsaProtectedConfigurationProvider, System.Configuration, Version=2.0.0.0,&#xD;&#xA;                    Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a,&#xD;&#xA;                    processorArchitecture=MSIL"


         keyContainerName="MyKeys"
         useMachineContainer="true" />
  </providers>
</configProtectedData>

-encrypt the connection strings

aspnet_regiis -pef "connectionStrings" "C:\Working\MyApplication" -prov RsaProvider

-give out the config file

-to decrypt

aspnet_regiis -pdf "connectionStrings" "C:\Working\MyApplication"

-export keys (will create keys.xml)

aspnet_regiis -pc "MyKeys" -exp

--On some other machine

-save keys.xml somewhere

-import the keys. make sure the name (e.g. MyKeys) is the same

aspnet_regiis -pi "MyKeys" keys.xml

-delete keys.xml!!!!!!!!!!!!!!

-give permissions to the service account if running as part of a webapp

e.g. aspnet_regiis -pa "PcscDev" "ASPNET"
