tools to encoding and decoding strings or cipher, may be can help in CTF
Simple tools for encoding and decoding strings, may be can little help in CTF
there are 2 variant in tools, list mode and argument mode
for list mode, you can running this tools with simple mode, only typing python file_name.pyc and you will know how to use it
for argument mode typing python file_name.pyc -h for more information
example :
python file_name.pyc -b64 - strings #base64 encode
python file_name.pyc -hex -d hexadecimal_strings #hexadecimal decode
python file_name.pyc -rev strings #reverse strings
python file_name.pyc -rot13 strings #rot13 shift
python file_name.pyc -caes -brute strings #caessar bruteforce for 0-26 shift
python file_name.pyc -caes strings -key (0-26) #caessar shift key value
python file_name.pyc -xor -brute strings #xor bruteforce 00-FF
python file_name.pyc -xor strings -key strings #xoring with key (only print printable char for results)
python file_name.pyc -md5 strings #hashing MD5
