1. Get the Python script accessible in your shell by entering the following command in the Terminal prompt: $ wget https://mercury.picoctf.net/static/2ac2139344d2e734d5d638ac928f1a8d/ende.py
$ man python
wget https://mercury.picoctf.net/static/2ac2139344d2e734d5d638ac928f1a8d/ende.py
wget https://mercury.picoctf.net/static/2ac2139344d2e734d5d638ac928f1a8d/pw.txt
wget https://mercury.picoctf.net/static/2ac2139344d2e734d5d638ac928f1a8d/flag.txt.en
4. 執行 cat pw.txt
以獲取解密過後的密碼
5. 複製密碼並在執行 python ende.py -d flag.txt.en
後貼上它
man python
python DECRYPT_ALGO -d DOCUMENT_TO_DECRYPT
( -d
是解密的意思; -e
是加密的意思 )
