Hello guys, have been intercepting some messages using fiddler, but can't seem to encrypt some encrypted messages. I need a little help on what is going on here. Here is the message and signature

 

{"signature":"b20bc61e421c04b4499d836f6322c46e933db7d7be22db62f762735f0a9069a0f23a6122ad3bfbee1607bc08fad53aa3f81078e5c0c138315ca66fd8f3695c21",

Hello Henry,

 

Is that an additional level of encryption used by the specific server-client? The signature and the message as shown don't say much - it would be better to post more information about the whole web session (request and response details).

 

The above said, make sure that you have FIddler configured to capture HTTPS (see this article) and that you have the Decode option turned on (in the Fiddler toolbar).

 

Regards,
Nick Iliev
