Library for performing frequency analysis to different formats

Project description

# Freqens
![TravisCI Status](https://magnum.travis-ci.com/BraulioVM/freqens.svg?token=qKkPGCZvRdJvJ693qC2L)
> Perform frequency analysis with python

### Example
````python
# break single byte xor encryption

from freqens import EnglishAnalyzer

def single_byte_xor(text, byte):
return "".join( chr(c ^ byte) for c in bytearray(text) )

with open("ciphertext.txt") as ciphertext_file:
ciphertext = ciphertext_file.read()
analyzer = EnglishAnalyzer()

possible_plaintexts = ( single_byte_xor(ciphertext, byte) for byte in range(256) )

answer = analyzer.choose_best(possible_plaintexts)

print answer[0] # Solution !!!
