Cannot Decrypt SSL/TLS Packets Using Pre-Master Secret Log File

Hi,

I'm trying to decode SSL/TLS packets in WireShark.

I set the Windows environmental variable SSLKEYLOGFILE=C:\Users\Dave\ssl-keys.log Just in case, I rebooted.

I then visited several web sites including the one I'm trying to decrypt messages. I did see the log file was written and the contents appear to be normal.

I then started a capture and used a curl command. I find the encrypted packets and my Pre-Master Secret log filename is correct, as shown in the banner above the packets.

Yet, I'm still not able to see decrypted messages.

What am I doing wrong?

Thanks,

Dave
