Cryptanalyze
WebCryptanalysis, as defined at the beginning of this article, is the art of deciphering or even forging communications that are secured by cryptography. History abounds with examples of the seriousness of the cryptographer’s failure and the cryptanalyst’s success. Web"One of the goals of cryptography is to develop schemes that cannot be cryptanalyze [sic] and the other is to cryptanalyze it. If the government outlaws this type of encryption schemes [sic] it will hinder the progress of cryptography and it would just force its development overseas." This is a good point.

We only need consider words longer than length 9, since we tested all the shorter words in step 1. We then try to decrypt the ciphertext with all possible dictionary words and record the keyword that resulted in plaintext with the highest quadgram fitness. high waisted corporate pants
