Hey guys, how can I convert this https://tlsfingerprint.io/id/bbf04e5f1881f506 back to JA3 String like this
ja3_string = "771,49196-49195-49200-49199-159-158-49188-49187-49192-49191-49162-49161-49172-49171-157-156-61-60-53-47-10,0-10-11-13-35-23-65281,29-23-24,0"
Is there a quick and dirty way to do that ?
