How to Password Protect the wallet.dat

Technology zcashd client
1

I am assuming that zcashd has a built-in way to password protect the wallet.dat file (and that I don’t have to use third party software to do that).

If that’s the case, can anyone tell me how to:

(1) Increase my keypool size so that my keypool contains 10,000 addresses.

(2) Add a password to my wallet so if my neighbor gets into my server room he can’t make off with my coins.

(3) Import that wallet to a second zcashd instance (on a different computer). Is this as simple as copying the wallet.dat file into the ~/.zcash/testnet3/ directory?

I appreciate your help!

I found the answer to number (2): You can increase the keypool size via the command:

~/zcash/./src/zcash-cli keypoolrefill 10000

Bitcoin Core does support wallet encryption, and the code for that is inherited by Zcash. However, it’s difficult to use without the UI in bitcoin-qt (see Step 2 at http://altoidnerd.com/2015/09/11/getting-started-with-bitcoin-the-right-way-bitcoin-core-and-linux/ ), and you might find the qt wallet difficult to compile for Zcash right now. If you manage it then please let us know.

The current wallet encryption does not support encrypting Zcash-specific keys. We’re working on that now: https://github.com/zcash/zcash/pull/1210

Encryption of Zcash-specific keys is likely to be supported in Beta 1.

@daira based on PR 1372 it looked like str4d added support for wallet encryption, but “zcash-cli encryptwallet” prints out an error saying that it always fails. Was this just user error, or is wallet encryption not supported yet?
