# Hashing in Python

## Examples

### Hashing script #1

Script example #1 from picoCTF

```python
#!/usr/bin/python
# -*- coding: latin-1 -*-

import hashlib
from pwn import *
import re

SERVER = 'saturn.picoctf.net'
PORT = 55823

def generateHash(word): 
    return hashlib.md5(word.encode()).hexdigest()

conn = remote(SERVER, PORT)
for i in range(3):
    question = conn.recvline().decode().strip()
    word = re.findall('Please md5 hash the text between quotes, excluding the quotes: \'(.*)\'', question)[0]
    answer = conn.recvline()
    hash = generateHash(word).encode()
    conn.sendline(hash)
    hashline = conn.recvline()
    correct = conn.recvline()
flag = conn.recvline().decode().strip()
conn.close()
print(flag)
```
