Just use the Winforms utility included in the zip… it can create the SSO application to store the keys, generate and save the keys, and then just specify the name of the SSO application in the pipeline component configuration.

Glenn,
If you want to allow the user to enter any text as the password, just modify the config tool to use Encoding.ASCII.GetBytes() on the text or something like that.

How do you get around the issue of having an ascii key? Can I convert the ascii key that I have? Or can I comment out the hexadecimal check?

The code above and my own code don’t represent the keys in the same format. My utility presents keys as a set of bytes presented in hexadecimal format; the utilities presented in the link you mention expect the keys to be simple strings that they then convert to bytes directly using an encoding (i.e. based on the ASCII codes of the characters in the string). Two completely different things. You need to handle them the same.

Tomas,
Thanks for the reply,
I am trying the code given at http://support.microsoft.com/kb/307010
to Decrypt the messages encrypted using your components, using the DES algorithm. But it just doesn’t work, although both are using the same algo.
1. The key that is generated by your utility is not accepted by this program, it says its size is not valid.
2. When I generate a key using that program, and try to make a SSO app using your utility with that key, your utility says its invalid.
So they dont seem to be using the same type of key. Can you please have a look at that code, and tell me how can I decrypt messages encrypted by your component using it Or give me some code which I can use in an application, to decrypt/encrypt messages encrypted/decrypted by your component.

Number 1 sounds like a permissions issue, maybe. Number 2 is strange, definitely haven’t seen those myself. It might be something in the name you’re using, perhaps? What name are you giving to your SSO application?
As to number 5, what you’d need is for the other application to decrypt the message using the same algorithm you encrypted it with, and the same set of keys. It is not necessary to actually use the same DLL; as long as you’re choosing the right options you can do it using the standard .NET crypto classes (which are what my pipeline components use underneath, anyway).

Toms,
I am a newbie to biztalk, I tried your encryption/decryption component with some success today, thanx for putting it for us. But I’ve few confusions where I got stuck using it.
1. When I make a SSO Configuration Application after running your application, it is made successfully, but when I try to open it, it breaks giving this error:
"The mapping does not exist. For Config Store applications, the config info has not been set".
2. What I did then was, Generated the keys, and then tried to save it, which gave me this error:
"The parameter is incorrect" at store.SetConfigInfo() method.
I worked around this, by hard coding the appName argument in the method to the config application I just made using the same form. It worked!
3. I then provided that applications name, in the send pipeline components SSOConfigAppName and deployed it.
4. It worked and it encrypted the outgoing message.
5. Now how do I decrypt that message to use it any application, would I need to use the same dll, that I used in Biztalk for that? and what about the errors I got mentioned in point 2 and 3, how can I get rid of them?
I’d be very grateful to you, if you take bit of your time out and answer my queries.
Thanks and Regards,
Sajid.
