I am aware that Cryptographers sometimes code in assembly to ensure their code is resistant to certain attacks such as side-channel attacks. What books on assembly programming would you recommend I get started with reading? For now I am mostly interested in x86_64 assembly in Linux since it is the assembly language of GNU/Linux servers--which use cryptographic code to serve clients.
I have the books so far:
x64 Assembly Language Step-by-Step: Programming with Linux 4th Edition
The Ghidra Book
What other books would you recommend?
