comment LUKS multiple key slots - what's the intuition?
Nope. Under the hypothesis that the encryption scheme used to encrypt the MasterSecretKey is secure. A standard encryption scheme does not leak any information about the plaintext if it is encrypted under multiple and different keys.

This question is not on topic here. By the way programming languages as python, ruby and many others have a inbuilt support for big numbers arithmetics. If you want still stick to C/C++ you can easily use a bignumber library (gmp for example)

yes, it is hex. when I wrote the answer I was from mobile and cannot check. But, as you said, the world is full of hex to dec converters: online or as a function in almost every programming language.
