Passphrase or password. In 2014, mining bitcoin was possible on a computer (he did on a mac) and it was all command line. That's what my friend was doing.
So we are trying to generate valid bitcoin addresses (not on the blockchain, nor wallets), to check if those addresses contain bitcoins.

I am trying to help him by having the script generate valid addresses but since 2014 the hashing to create the private/public keys have been changed so
I am trying to figure out if the script above is valid to create bitcoin addresses created at that time.

Does it make sense?
thx for the comments!

It depends on how your friend used the passphrase to generate addresses. I'm assuming that you didn't use any wallets like Electrum, Bitcoin-qt (back then), Armory, etc? The hashing hasn't changed and P2SH and P2PKH were the most prominent address types back then. If you cannot remember how it was generated, then it would likely just be like finding a needle in a haystack.
