Error when trying to use MicroFour.StrataFrame.Security.Encryption.TripleDESWrapper

Hi all.

I am trying to use this class to encrypt and decrypt parameters being passed to a web page in the Query String.

I used this code to Encrypt the value of the pk:

I am using this code in my ListView's RowPopulating event to create an "Edit" hyperlink in the first column:

string EncrytedSignOffID = _3des.Encrypt(e.BusinessObject["sign_off_id"].ToString());

e.Values[0].DisplayValue = "<a href='EditSignOff.aspx?pk=" + EncrytedSignOffID + "&project_id=" + Request["pk"] + "'>Edit</a>";

When I click on the hyperlink to go to the Edit Page, I am trying to use this code in the Edit Page's Page_Load to decrypt the PK:

MicroFour.StrataFrame.Security.Encryption.TripleDESWrapper _3des = new MicroFour.StrataFrame.Security.Encryption.TripleDESWrapper();

String DecryptedSignOffID = _3des.Decrypt(Request["pk"].ToString());

But I wind up with this error instead of the web page:

System.FormatException was unhandled by user code
Message=Invalid length for a Base-64 char array.

       at System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint)
InnerException:

Can someone help me out here? What do I need to do to make this work?

TIA.

Marcia.

Thanks for posting the solution dude. I was also experienced the same kind of problem. But now I also got this figured out.

Here I am talking to myself again :)

I am posting this just in case someone else runs into the same problem:

I finally got this figured out. All I needed was this on the Decrypt:

String DecryptedSignOffID = _3des.Decrypt(Request["pk"].Replace(" ", "+"));
