I know Kyle personally. He is super smart, incredibly humble, and willing to teach. And I always admire anyone taking the initiative to try and produce something useful.

In response to Jabbles, this is from his (work in progress) book. Page 7.

  // Implement the standard padding scheme for block ciphers. This
  // scheme uses 0x80 as the first non-NULL padding byte, and 0x00 to
  // pad out the data to a multiple of the block length as required.
  // If the message is a multiple of the block size, add a full block
  // of padding. Note that the message is copied, and the original
  // isn't touched.

As anyone who has written technical material knows, your drafts tend to be error prone and you rely heavily on others to help catch your mistakes. Technical editors are the normal tool utilized by the traditional publishing world. As this is a leanpub book, I feel that the responsibility generally falls on the community. Those who have paid for the book and want to see it succeed.

I personally have purchased this book as well as reported errors to Kyle.

I'd encourage anyone with questions or comments to reach out to Kyle. He is quick to respond.
