Mar 10, 2017 Simple Vigenere cipher in Python (and 3). Last part of my series about Vigenere cipher. (3 post in a row? I am proud of myself:-P) In my previous posts I already showed how to use Vigenere square to encrypt/decrypt text. $ python Vigenereciphermod.py Key: WHITE Decode text: - Input text: en un lugar de la mancha de cuyo nombre no.

defencrypt(plaintext, key):

key_as_int= [ord(i) foriinkey]

plaintext_int= [ord(i) foriinplaintext]

ciphertext='

foriinrange(len(plaintext_int)):

value= (plaintext_int[i] +key_as_int[i%key_length]) %26

ciphertext+=chr(value+65)

returnciphertext

defdecrypt(ciphertext, key):

key_length=len(key)

key_as_int= [ord(i) foriinkey]

ciphertext_int= [ord(i) foriinciphertext]

plaintext='

foriinrange(len(ciphertext_int)):

value= (ciphertext_int[i] -key_as_int[i%key_length]) %26

plaintext+=chr(value+65)

returnplaintext

I think there are limitations here with lower case and capital letters. /bitdefender-antivirus-plus-2013-license-key-generator-free-download.html. You'd need to check for .lower(), and also simply pass the character through if it doesn't match A-Z.

I wrote one that handles all default ASCII characters (95):

For example:

@flipperbw ,
I'm trying to make a similar program. Would you mind reposting your code with comments; I'm having a bit of a hard time following it.
Thanks.

I implemented this some years ago, along with a tabula recta generator so you can do it by hand (for fun!)

Hello!
in your first code (the one that starts like:
def vig(txt=', key=', typ='d'):
if not txt:
print 'Needs text')
there is a thing called 'ret_text'
what does it do? I am trying to get inputs and then encode/decode it but I am not sure how I should do that, if only I knew what ret_text does. Can you specify it?
Thanks!
