Interesting question, thanks Koen!

I had it wrong because, like Mohammed, I had to google - and I found this reference that appears to contradict the reference Koen used:

In an Integration Services package, the following information is defined as sensitive:
(...)
* Any variable that is marked as sensitive. The marking of variables is controlled by Integration Services.
(...)
Also, for the protection levels that use a password, Integration Services uses the Triple DES cipher algorithm with a key length of 192 bits, available in the .NET Framework Class Library (FCL).

Can anyone who knows more about SSIS than I do (i.e.: something) comment on this apparent contradiction?

Never read that MSDN article, but I can see why it leads to confusion.

My question is about the encryption used inside the database engine (SSISDB) to encrypt parameter values. This is a new feature in SQL 2012 and somewhat equivalent to the protection level ServerStorage.

The protection levels however specify how sensitive data (so not only parameter values, but for example passwords in connection strings) are encrypted and this has nothing to do with the SSISDB (protection levels are more a feature of the legacy deployment model). Protection levels can be enforced on packages stored on the filesystem by Integration Services, so it is no way coupled to the encryption inside the SSISDB.

But I understand the confusion 🙂

Everything is awesome!

Great question!!! Glad to see some of the more obscure stuff from 2012. Makes the research more challenging since there is not much coverage of this stuff. Keep them coming Koen.

Thanks for the question, I learned something.... was confused because I hit the same google link that others above did and figured Triple DES was the trick.

Good question, nice to see more 2012 QotDs here.

I also googled for possible answers and stumbled upon the following article:

http://msdn.microsoft.com/en-us/library/gg471508.aspx

It states the answer, but it made me think if it was only for "configuration values". Glad to find out it was right.

Thanks for your explanation, Koen.

It must have changed for 2012 - 2005 had Triple DES.

I did not check whether it is still true, and I got it wrong.
