Get contract bytecode and creator from contract address on Geth console

Question

I can get contract bytecode and it's creator via this URL. https://etherscan.io/address/CONTRACT_ADDRESS
[example: https://etherscan.io/address/0x5a3e58c7cf09217d2a5385bf96c02673ed1187bb#code]

I would like to get it on geth console but not found solution during several days. I think there will be a way since etherscan provide it.
My try was using web3, but no success, any kind of help will be much appreciate!

Answer 1

The bytecode should be accessible via getCode. I'm not aware of an efficient way to find the contract's creator (the originator of the transaction that created the contract). I believe you would have to just scan transactions.
