Can --batch mode return both address and private key pair?

[xavier4040]

Hi

I am currently testing bitcoin-tool for a project.

I have 2 questions :

• I would like to know if the current version of bitcoin-tool permits to return both address and private key pairs ? I have tried to use it but from my trial, it seems that the batch mode can only return one output-type. Which is a bit annoying since only having an address without the associated private key is not very useful in terms of bitcoin usage.

• How hard would it be to modify the code in order to permit to --batch mode to return both address and private key pairs?

Thanks
Xavier

Your first question is possible with --output-type all, for example:

./bitcoin-tool \
  --input $(openssl rand 32 -hex) \
  --input-type private-key \
  --input-format hex \
  --network bitcoin \
  --public-key-compression compressed \
  --output-type all

Will output in the following format:

address.hex:00854bb7dfddbfccb8282e802836c20207156a8f0d

This does not currently work for --batch mode, as I think it'd be more sense to output selected items on the same row, rather than consecutive rows, which makes parsing harder. Shouldn't be too hard to change that behaviour, and I'd welcome any suggestions on the design.

Hi

Thanks for your reply.

Yes I saw the --output-type all option, which returns a lot of informations.

From my point of view, the two main components of a "bitcoin identity" are the address and the private key (WIF). This is what is used by end users.

The workaround I found to the --batch operation is to run 2 bitcoin-tool commands, one for returning addresses, the other for returning private keys (both from same hex numbers file), and then merge/join the two files. So if bitcoin-tool could return both values on the same line, that would be perfect.

I agree with you with returning the selected items on the same row. It would make it a lot easier to handle. I think that CSV style is the most common and easy to use format/design. For example [Address;PrivateKey].

So for your example, each line could return something like this (if semicolon is used as delimiter):
1D9oaWbrJ2bRn5a7XkexLTFge7Ua8iLkEJ;KwuwezTsotYEjgfSX7Q9UpLPNHyLJPedER88PNp1QFtBsfqGbxmP

The idea is to just keep it simple.
