bitcoind rejects WIFs that do not belong to the current network. Or so it seems. Here's an example for you to reproduce using a mainnet WIF:
$ ./btcctl --regtest --rpcuser=aaaa --rpcpass=bbbb signmessagewithprivkey 5HueCGU8rMjxEXxiPuD5BDku4MkFqeZyd4dZ1jvhTVqvbTLvyTJ iamsatoshi
G+brEqKGQgPCSkPJrBau7x32eFhT3Y5YXdEXKG2bg2E2Tqi0lU54t+rYrEezLcSDLS4TM+/AO8a3A9ybAfvyMLY=
$ bitcoin-cli -regtest signmessagewithprivkey 5HueCGU8rMjxEXxiPuD5BDku4MkFqeZyd4dZ1jvhTVqvbTLvyTJ iamsatoshi
error code: -5
error message:
Invalid private keyThe fix would be to simply check wif.IsForNet(s.cfg.ChainParams).

Yes this was the case. Fixed by checking wif.IsForNet(s.cfg.ChainParams) as you suggested.
Reuse the Bitcoin message signature header const also in verifymessage.

Looks good to me/tested locally against 0.20.0/0.19.0 (on bitcoind side). Since I'm not as familiar with btcec, would prefer to have someone else look over it as well |
