## Prologue
This challenge wasn't a hard one, found the solution on Google, just had to make some changes.
## Ciphertext
Ciphertext contained hashes like:
```

```
Quick google search returned rainbow tables on SHA-256 and MD5.
Quickly making a rainbow-table and feeding the file through it returns a long file, so we just grepped it and got the flag.
## Source code
```python
import hashlib
f = open('ct.txt', 'r')
md5s = {}
sha256s = {}
for i in range(256):
md5s[hashlib.md5(chr(i)).hexdigest()] = chr(i)
sha256s[hashlib.sha256(chr(i)).hexdigest()] = chr(i)
text = ""
a = f.read().split(" ")
for c in a:
if c in md5s:
text += md5s[c]
if c in sha256s:
text += sha256s[c]
print text
```
## Flag
