## Prologue
This challenge wasn't a hard one, found the solution on Google, just had to make some changes.
## Ciphertext
Ciphertext contained hashes like:
```148de9c5a7a44d19e56cd9ae1a554bf67847afb0c58f6e12fa29ac7ddfca9940 e1671797c52e15f763380b45e841ec32```
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
```pythonimport hashlibf = 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
```Congratulations!_T#e_Flag_Is_F#{Y3aH_Y0u_kN0w_mD5_4Nd_Sh4256}```
