Can QuartzServer NET decrypts connection string in config file? - encryption

Question

I'm using Quartz.Server.exe 2.X as job executor.
I'm using Quartz.Server.exe.config to configure quartz.
<quartz >
<add key="quartz.scheduler.instanceName" value="AlyCE_LROScheduler" />
<add key="quartz.jobStore.type" value="Quartz.Impl.AdoJobStore.JobStoreTX, Quartz" />
<add key="quartz.jobStore.useProperties" value="true" />
<add key="quartz.jobStore.driverDelegateType" value="Quartz.Impl.AdoJobStore.SqlServerDelegate, Quartz" />
<add key="quartz.jobStore.tablePrefix" value="QUARTZ_" />
<add key="quartz.jobStore.dataSource" value="defaultDS" />
<add key="quartz.jobStore.lockHandler.type" value="Quartz.Impl.AdoJobStore.UpdateLockRowSemaphore, Quartz" />
<add key="quartz.dataSource.defaultDS.provider" value="SqlServer-20" />
<add key="quartz.dataSource.defaultDS.connectionString" value="my connection string to encrypt/decrypt" />
</quartz>
All works fine. Now I'd like to encrypt the connection string for security reason.
Is there a way to let Quartz.Server.exe to understand encrypted connection string?
Thanks

Answer 1

I solved.
I removed the connection string quartz property and I added the connectionProvider.type property, that let me to override the standard Quartz.Impl.AdoJobStore.Common.DbProvider.
So I am able to decrypt my connection string.
So my config looks like this:
<quartz >
<!-- thread pool info -->
<add key="quartz.threadPool.type" value="Quartz.Simpl.SimpleThreadPool, Quartz" />
<!-- job store info -->
<add key="quartz.jobStore.type" value="Quartz.Impl.AdoJobStore.JobStoreTX, Quartz" />
<add key="quartz.jobStore.useProperties" value="true" />
<add key="quartz.jobStore.driverDelegateType" value="Quartz.Impl.AdoJobStore.SqlServerDelegate, Quartz" />
<add key="quartz.jobStore.tablePrefix" value="QUARTZ_" />
<add key="quartz.jobStore.dataSource" value="defaultDS" />
<add key="quartz.jobStore.lockHandler.type" value="Quartz.Impl.AdoJobStore.UpdateLockRowSemaphore, Quartz" />
<add key="quartz.dataSource.defaultDS.connectionProvider.type" value="MyDll.MyDbProvider, MyDll" />
</quartz>
<connectionStrings>
<add key="myConnString" connectionString="crypted"/>
</connectionStrings>
Then I create new class library project where I created this class:
public class MyDbProvider : DbProvider
{
public MyDbProvider() : base("SqlServer-20", MyHelper.GetConnectionString()) { }
}
public static class MyHelper
{
public static string GetConnectionString()
{
//here i decrypt my connection string from app.config file
}
}
MyDll.dll must be in the same directory of Quartz.Server.exe .
Hope this can help someone!
