Periodic Polyalphabetic Systems

Vigenère

  • KE/001* (Keith Edkins 2004-Feb-22)

    Ran Vigenère with all words in 173K list as keyword. Using KRYPTOS alphabets as in sections 1 & 2. Grading results on occurence of singles, digrams and trigrams. Repeated with plain alphabets. No interesting results.
