About this document

Kasiski Test for Vigenère Cipher Analysis by Anand Sithan is a document available to read on EtoBox.

1. The document describes the Kasiski test, a cryptanalysis technique for determining the length of the keyword in a Vigenère cipher. 2. The test works by searching the ciphertext for repeating strings (trigraphs or longer) whose distance apart is a multiple of the keyword length. 3. Finding such repetitions indicates the strings were encrypted with the same section of the keyword, revealing clues about its length.
