Getting started

git clone [email protected]:martcl/autojail.git
pip install ./autojail
autojail -h

Examples

Open a file with a blacklist

autojail -o flag.txt -b open "'" '"'

print(*__builtins__.__dict__[chr(111)+chr(112)+chr(101)+chr(110)](chr(102)+chr(108)+chr(97)+chr(103)+chr(46)+chr(116)+chr(120)+chr(116)))

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)))

Create any number using whitelist

autojail -n 22 -w 0 1 b

0b10110

Usage
