Caesar Salad
The typical format of flags in this contest was ctfZero{leet-speak}
. Going by the same format, we can quickly observe that the ROT cipher shift in this question was 14. Alternatively, we can also write a simple python script to brute-force ROT cipher decryption.
#!/usr/bin/python3
string = input("Enter encrypted string:\n")
for i in range(1, 26):
decrypt = ""
for j in string:
decrypt += chr(ord("a") + (ord(j) - ord("a") + i) % 26)
print("shift: " + str(i) + " decrypted string: " + decrypt)
