Cipher text example

edit

I reverted a bad edit with the incorrect cipher text. Here's some basic python code showing the calculation

>>> f=lambda (x,y):chr((ord(x)-ord('a')+ord(y)-ord('A')) % 26 + ord('A'))
>>> f(('f', 'E'))
'J'
>>> map(f,zip(list('fleeatonce'),list('ERRORSCANO')))
['J', 'C', 'V', 'S', 'R', 'L', 'Q', 'N', 'P', 'S']

Note I only had to revert the bad first four characters of the cipher-string; the rest was ok originally. Jimbobl (talk) 14:44, 7 September 2011 (UTC)Reply

BDA reference

edit

I'm not seeing any other reference to BDA different from it outside of this article. Does anyone know where that came from? Rusca8 (talk) 16:36, 20 October 2019 (UTC)Reply
