• Caesar cypher solver
• Xor cypher solver

usage:

python3 xor_brute_force.py

• --r [regex pattern to look for]
• --l [max key length]

i.e.: python3 xor_brute_force.py --f "something.txt" --r ".this is totally a pattern." --l 3

Caesar cypher solver usage:

python3 caesar.py --f [filename] and voilà:
