Lightboard Lessons: Secure Data Tokenization

@Mats Nystrom, I reached out to the guys who contributed to the code and here's some feedback from them:

We are not supposed to have a send or receive, the request is being parsed and we are simply releasing the TCP connection:

TCP::payload replace 0 [TCP::payload length] $newdata3 
TCP::release

Then parsing it back in the response from voltage:
when HTTP_RESPONSE {  Collect HTTP response data

by the way, there is a small typo there in the example as you are saying you are ending CLIENT_DATA and you are only ending the IF statement … that might throw people off:


when CLIENT_DATA { 
if {[TCP::payload] contains "GET /tokenize?"} { 
 Optional logging for debugging log local0. "Tokenization GET request" 
} else { log local0. "Some other request - let it through" TCP::release return 

} end when CLIENT_DATA 

 get the query string: this what we want to encrypt set plaintext [findstr [TCP::payload] "data=" 5 "&"]

Let me know if you have any other questions. Thanks!
