If my wallet lock is the password entered when sending stakes or coins, I enter the password for a single stake or when sending coins, is there another step to activate it? before doing dummprivkey
An encrypted Qtum Core wallet has a single passphrase that can be used to fully unlock the wallet, or unlock the wallet for staking only. To send coins or dump the private key the wallet must be fully unlocked.
To fully unlock the Qtum-Qt GUI wallet go to Settings - Unlock wallet and "untick" the little box "For staking only." Then enter the passphrase and click OK.
To fully unlock the qtumd daemon wallet using qtum-cli enter the command as appropriate for your operating system:
qtum-cli walletpassphrase "your_passphrase" 600
Here the wallet would be fully unlocked for 600 seconds.
Thank you very much for JB395 information.
