bitcoin-cli: -stdinwalletpassphrase and non-echo stdin passwords #13716

kallewoof · 2018-07-19T14:52:07Z

This PR

adds -stdinwalletpassphrase for use with walletpasshprase(change)
adds no-echo for passwords (-stdinrpcpass and above)

It may not be ideal, but it's better than having to clear the screen whenever you unlock the wallet.

There are conflicting pull requests:

this one adds new features and, as a side effect, fixes one of two bugs in bitcoin-cli --help output;
#13879 fixes all found bugs in bitcoin-cli --help output and is safe for the whole code.

So, #13879 can be merged regardless of this pull request.

src/util.cpp

As this is only used in bitcoin-cli, it doesn't need to be in util.cpp (which is shared between the server and client), would be better in a client-specific utility, e.g. compat/noecho.{cpp,h} or something like that, that is only linked into -cli.

Good point. Fixing.

src/util.cpp

is this generally supported on all UNIX, or does it need checks in the build system?

termios.h? It seems to be pretty standard FWICT.

going to test on FreeBSD and OpenBSD

src/bitcoin-cli.cpp

need to re-enable echoing before the normal -stdin processing

make sure that this is not called unless either -stdinrpcpass or -stdinwalletpassphrase is called to avoid interfering with scripts that pipe in data, not attached to a TTY

Good points. Addressed both.

@Sjors

Nit: return \n after password entry.

Hitting enter adds a newline on my mac. Where do you want one to be added? After the std::getline call?

Sjors · 2019-02-13T09:17:25Z

@kallewoof it didn't return a new line for me (macOS 10.14.3):

re-tACK 110e821

kallewoof · 2019-02-14T05:51:59Z

Oh, okay! So this is the case for pre-existing -stdinrpcpass as well. Fixed in d1688c9.

Sjors · 2019-02-14T15:59:47Z

src/bitcoin-cli.cpp

you could use fputs here (same below) and avoid introducing the locale dependency exception

tfm::format(std::cerr, ... should work as well

D'oh, yeah. Removing linter changes and using fputs.

laanwj · 2019-09-30T12:06:56Z

src/bitcoin-cli.cpp

please only print this extra newline if stdin terminal is detected, and not when, say, piping in from a script (same below 2x)

Understood. I think the latest version achieves this. (See StdinTerminal().)

$ ./bitcoin-cli -datadir=d -regtest encryptwallet foobar38 wallet encrypted; The keypool has been flushed and a new HD seed was generated (if you are using HD). You need to make a new backup. $ ./bitcoin-cli -datadir=d -regtest -stdinwalletpassphrase walletpassphrase 10 Wallet passphrase> $ echo foobar38 | ./bitcoin-cli -datadir=d -regtest -stdinwalletpassphrase walletpassphrase 10 $ echo xfoobar38 | ./bitcoin-cli -datadir=d -regtest -stdinwalletpassphrase walletpassphrase 10 error code: -14 error message: Error: The wallet passphrase entered was incorrect.
