AutoJail is a tool for automatically solving python jail CTF challenges. This program takes in a blacklist/whitelist and generates valid python that, when ran, will execute the desired code.
git clone [email protected]:martcl/autojail.git
pip install ./autojail
autojail -h
Open a file with a blacklist
autojail -o flag.txt -b open "'" '"'

Generate strings
autojail --string HEI --blacklist H c ᶜ 0 7
'%\143'%(int(repr(int(not())+(int(not())+int(not()))+(int(not())+int(not()))**(int(not())+int(not())))+repr(2)))+'%\143'%(69)+'%\143'%(int(repr(int(not())+(int(not())+int(not()))+(int(not())+int(not()))**(int(not())+int(not())))+repr(3)))
