QUOTE

TL;DR

  • I bought my first ebook from amazon
  • Amazon’s Kindle Android app was really buggy and crashed a bunch
  • Tried to download my book to use with a functioning reader app
  • Realized Amazon no longer lets you do that
  • Decided to reverse engineer their obfuscation system out of spite
  • Discovered multiple layers of protection including randomized alphabets
  • Defeated all of them with font matching wizardry
