chunklate's Issues

Not an issue! - Just a compliment

I don't understand how such a good tool isn't known and doesn't have as many stars as other good tools like nmap, netexec, etc.
I will strive to promote the Chunklate tool whenever I can.

Can you add an option to just fix the crc and do it silently(without any text output)

Im working on a program and would love to see something like this implemented! :) please tell me if you can do this .

I test itxt.png，but can not generate a new image

I test itxt.png，but can not generate a new image，also I can't find the generated image in the code.Did the code not generate the repair image part?
