None of it is customized.  All of it is industry standard.

Most of the hashes in Bitcoin are SHA-256 (or a SHA-256 hash of a SHA-256 hash depending on where it's being used).

Be aware, however, that Bitcoin also uses a RIPEMD-160 hash when creating a Bitcoin Address.

thanks all, what i mean is it a direct usage approach of SHA-256 or it's some sort of customized SHA algorithm, if general SHA-2 algorithm there are plenty of resources if not, please point me where i can read more about it.

It's just two rounds of SHA-256, the standard stuff.

is there any source where i can read the core bitcoin hashing algorithm in depth?

Thanks in advance.

How much depth do you want?

What do you mean the core bitcoin hashing algorithm? You mean to create bitcoin addresses? https://en.bitcoin.it/wiki/Technical_background_of_Bitcoin_addresses

A hash in Bitcoin corresponds to two applications of SHA-256.
