Anyone have experience with RC4 encryption?

[Tom Gilbert]

Here is what I am trying to do:

We use Phillips iSite as our PACS system.

We are sending a link in the HL7 message (ORU) with the result to an outside EMR (eClinical Works).  When they click the link it will take them to our PACS and have the ability to view images.  I am trying to encrypt our MRN and Accesssion Number so it is encryped as it comes over the internet.

Our PACS wants us to use RC4 to encrypt and have it in a Ascii format.  I was given a Key to use when I encrypt.  Does anyone have any thoughts on this…

I am trying to do this through Tcl.

I have pulled down the RC4 package and put it in the Tcl folder under integrator.

This seems like the wrong way to handle this problem. Why don’t you use HTTPS to encrypt the entire request?

Also, you only seem to be asking about encrypting the request that EMR makes to the PACS. What about the transfer of the message from Cloverleaf to EMR?

Hi Tom,

Were you able to find the solution to your encryption issue?

We are in the same shoes now requiring exactly the same thing.

Let me know.

Thanks.
