bitsign

A tool to generate bitcoin keys, sign and verify messages using bitcoin keys. (compatible with Bitcoin Core)

Installation

From Sources

With Rust's package manager cargo, you can install bitsign via:

cargo install --force bitsign

Usage

Generating keys: bitsign generate

The tool will draw randomness from the OS, but for the paranoid users it also lets you input your own entropy by hitting random keys at stdin.

Optionally you can pass --type for p2pkh/p2wpkh/p2shwpkh [default: p2wpkh].
and --net for bitcoin/regtest/testnet [default: bitcoin].
or even --uncompressed(If for some reason you really need uncompressed keys).

Sign a message: bitsign sign <privkey> <message>

Verify a message: bitsign verify <address> <message> <signature>

This tool will also try and verify messages with p2kpkh and p2shwpkh but bear in mind that Bitcoin Core won't accept that same verification (a warning will get printed).

Example

$ bitsign generate --type p2pkh
Input your own randomness by hitting keys randomly and then hit 'enter' when you're done: (This will be on top of random entropy from the OS)
