This book guides the user through an understanding of why large-scale password leaks happen, what methods exist to prevent them, and how cryptography can be used to eliminate large-scale password leaks entirely.
This new cryptography is called OPAQUE, and it uses zero-knowledge proofs to create a secure key exchange without ever sending the user's password across the Internet.

The second half of the book explains how to implement the OPAQUE protocol line-by-line using Type...
