Is Bruce Schneier Applied Cryptography, Second ed. up to date? I like Applied Cryptography, and I am returning to cryptography after a while. So I am wondering if that book is up to date or can be complemented with other references.
I am looking for a book, authoritative, well documented. Possibly including code.
I would prefer to have a book as a reference, instead of asking naive questions to the community for something I could find in a book like Schneier’s. I wish to ask the community for help to understanding what’s in the book or ask for help on specific real world problems.
I have a background in cryptography, number theory, data, and coding.
The Applied Cryptography Second Edition goes back to 1996.  Although there is a 20th-anniversary edition, 2015, it is not updated as one thought. If you look for Schneier's style, you may look at the

Cryptography Engineering: Design Principles and Practical Applications, 2010

There is also another nice practical book by Jean-Philippe Aumasson

Serious Cryptography: A Practical Introduction to Modern Encryption, 2017

And, another one by David Wong as pointed by SAI Peregrinus

Real-World Cryptography, 2019

All three books are good for one to understand the cryptographic techniques at work in common tools, frameworks, and protocols. This will help to make excellent security choices for systems and applications. They are especially good for engineers and IT.
