# Hello Rules!! (10 PTS)
### Description
>Find the flag in the rule page
Flag: ```SharifCTF{053e3df6d82735fa4f708f3d61f2c903}```
### Solution
As description said we're going to the rule page.

We should carefully read the page and see a line at the bottom:
```
The flag of this challenge is SharifCTF{MD5(lowercase(Hello_Rules))}
```
Understandable, right?

>>> from hashlib import md5
>>> str = 'Hello_Rules'.lower()
>>> hash = md5(str.encode()).hexdigest()
>>> 'SharifCTF{' + hash + '}'
'SharifCTF{053e3df6d82735fa4f708f3d61f2c903}'
