# The Count

### El problema

Nos dan una palabra y teniendo en cuenta que las letras equivalen a a=0, b=1 (...) debemos hacer la suma y enviarla en menos de 5 segundos para obtener la flag

```bash
└─$ nc code.deadface.io 50000
DEADFACE gatekeeper: Let us see how good your programming skills are.
If a = 0, b = 1, c = 2, etc.. Tell me what the sum of this word is:

 You have 5 seconds to give me an answer.

Your word is: attend
Too slow!! Word has been reset!
    
Stop wasting my time.
Connection Closed.

```

### Solución

Escribí un script en python+3 que toma la palabra enviada, la calcula en base al valor de cada letra y la suma para enviarla. Una vez enviada nos envian la flag.

{% hint style="info" %}
Utilice ord(letra)-ord(a) para convertir las letras a numeros empezando por a=0
{% endhint %}

```python
from pwn import *

def sumWords(palabra):
    suma=0
    for  i in palabra:
        suma += ord(i)-(ord('a'))
    return suma
        

p = remote('code.deadface.io', 50000)
word = p.recvlines(6)[5].split(b': ')
suma = sumWords(word[1].decode('utf'))
log.info('Word: '+ word[1].decode('utf') + ' | Sum: ' + str(suma))
p.sendline(str(suma).encode())
p.recvline()
log.info('Flag >> ' + p.recvline().decode('utf'))

p.close()
```
