Editing dumped file then client-replay about mitmproxy HOT 5 CLOSED

Sorry, you can't just edit the mitmdump files by hand. The data segment headers encode the length of the following data chunk. If you change a portion of it, and change the length, you've corrupted the file. So please treat the data dumps as binary data, just like a pcap dump. If you need to, you can edit the dump using mitmproxy, by reading the dump in, changing it in the interface, and then writing it to disk again.

I tried that too. Same thing. Invalid data format.

OK. You'll have to give me a lot more information though. First, a step-by-step on how to reproduce the issue. Second, what platform you're running on, what version of mitmproxy you're using, etc.

I know how to modify the flow in mitmproxy, however, how do I read in the flow file, edit it and save it using libmproxy?

Hi @wimbledon,

you can read an existing dump file using mitmproxy -r dumpfile (optionall with -n). Having modified the flows, you can save them to a new file by pressing w -> a in the flow list.

Cheers,
