How deeply does Hacking Cryptography cover AES?

Defines AES’s structure, key sizes, and security status, then stops short of detailing its round transformations or algorithms.

AES

As explained in Hacking Cryptography

A symmetric block-cipher standard adopted for protecting data in applications ranging from financial transactions to classified information.

AES is a symmetric block-cipher standard for protecting data, including financial transactions and classified information. Also called Rijndael, it replaced DES after a public selection process and remains secure against known practical attacks when implemented correctly. section 1.3 section 5.1

AES defines a family of configurations with these core properties:

Operates on a 4×4 array of bytes. section 5.1
Uses a fixed 128-bit block size. section 5.1
Supports 128-, 192-, and 256-bit keys. section 5.1

When correct AES still fails

An attacker need not break AES’s mathematical theory. A padding-related implementation bug can expose plaintext encrypted by an AES-based system, making the engineering around the cipher the practical attack surface. section 1.3 section 5.1

The operational rule is simple: distinguish the cipher from the system using it. Correctly implemented AES has no known practical attacks, while bugs and unanticipated interactions with machines and data can repeatedly compromise AES-based systems. section 1.3
