Makeshift

Personal Rating: Easy

Unfortunately, my notes for this one are missing, but writing the decryptor was rather easy.

This was the encryptor:

from secret import FLAG

flag = FLAG[::-1]
new_flag = ''

for i in range(0, len(flag), 3):
    new_flag += flag[i+1]
    new_flag += flag[i+2]
    new_flag += flag[i]

print(new_flag)

This was the decryptor I wrote:

flag = '!?}De!e3d_5n_nipaOw_3eTR3bt4{_THB'
new_flag = ''

for i in range(0, len(flag), 3):
    new_flag += flag[i+1]
    new_flag += flag[i+2]
    new_flag += flag[i]

print(new_flag)
