intro

When working on an ad-hoc anti-fraud projects on order side, I learned a lot about Cryptology. So I plan to share the knowledge. This talk will be about some Cryptology basics for Web Developers to know, so you don't look like an idiot when you talk about Cryptology or implement features using crypto-js. (That's what I did) Outline:

• Signing or Encryption?
• How does HTTPS work behind the scene? (Will involve TLS/SSL)
• Block Cipher basics (what is AES and how to use it), including:
  • What is key, blockand iv?
  • Common practices when you try to encrypt something. (very practical, will be my main focus)
• Cryptology history (Can trace back to 700 B.C.) I read some books about this when I was a kid. Will decide if we add in or not depends on timing. Low priority.
  • I wish to at least tell the illegal shirt story

resources

Some documentation and my practice experience.
