### **Title:** crypto/one-more-time-pad
**Hint:** Just a XOR challenge
**Solution:**\If we look through the code we can see that the cipher text is just a XOR of msg and key.
```cipher_text(ct) = message(key) XOR cipher_key(pt)
then,message(key) = cipher_text(ct) XOR cipher_key(pt)```
Below, [reverse.py](./reverse.py) just does that to get our flag.
**Exploit:** ./reverse.py
**Flag:** `lactf{b4by_h1t_m3_0ne_m0r3_t1m3}`
