A Rebellious Journey by Rebecca

 I have just finished reading Tom Felton's autobiography 'Beyond the Wand'. It was unlike any other biography I have read in the past. This felt very much like sitting down with a friend and talking about stories of their life, their career, their loves.  As a filmmaker, I appreciated all the behind the scenes stories from his life on set of Harry Potter, as well as his progression afterwards. But as a human being, I appreciated the raw honesty within the writing, especially the final chapters where he discusses his mental health decline. The words were delicately chosen and hit home, enough to bring a tear to my eye.  I would 100% recommend this book.

 Enigma:- the code was changed daily and was cracked using a machine.  ADFGVX:- These cipher text sound different from each other when used in morse code. This is to reduce user error. This method uses a 6 x 6 polybius square.  Playfair:- The alphabet is written in a diagram- but excluding J as the diagram is a 5x5 square. J is replaced by I. The text is split into pairs- if it's odd numbered then a z is added to the end.  Book Cipher:- I like the book cipher. You both need the same book and would send numbers for the pages, line in the book etc. to form the message.  Vigenere Cipher:- Uses a series of a different Caesar Ciphers.  Caesar Cipher:- Letters are shifted a certain number of spaces.... so a becomes d.  Homophonic Cipher:- The plaintext is replaced multiple different cipher text letters.  During World War 2, the Enigma machine was cracked by a group of code-breakers led by Alan Turing at Bletchley Park.
