Cracking Codes with Python teaches complete beginners how to program in the Python programming language. The book features the source code to several ciphers and hacking programs for these ciphers. The programs include the Caesar cipher, transposition cipher, simple substitution cipher, multiplicative & affine ciphers, Vigenere cipher, and hacking programs for each of these ciphers. The final chapters cover the modern RSA cipher and public key cryptography.
Cracking Codes with Python is the 2nd edition of the previously-titled book, Hacking Secret Ciphers with Python.

You'll receive a free ebook to read, and upon posting a review to Amazon, you will receive a complementary print review copy of the book. (UPDATE: There's been a large amount of interest, and I can't guarantee you'll get a print book. However, I can definitely send you an ebook to review.)
To demonstrate that you will be able to write a review, please send me a link to an Amazon, Goodreads, or Powells review you have written before. If you haven't written an Amazon review before, please explicitly tell me in your email you have an Amazon account and can post reviews. Also, please include the word "walrus" in the subject of your email so I know you read this. I'm happy to send out books to reviewers, but I can only respond to serious inquiries from folks who have read these instructions.

The only requirements are that the review be a minimum of 100 words, you must live within the United States (due to shipping costs), you must have purchased $50 off Amazon in the last year (Amazon has this requirement before you can write a review), and that you email me first before writing the review.
