walletpassphrase "passphrase" timeout

Stores the wallet decryption key in memory for 'timeout' seconds.
This is needed prior to performing transactions related to private keys such as sending bitcoins

1. "passphrase" (string, required) The wallet passphrase
2. timeout (numeric, required) The time to keep the decryption key in seconds. Limited to at most 1073741824 (2^30) seconds.
Any value greater than 1073741824 seconds will be set to 1073741824 seconds.

Issuing the walletpassphrase command while the wallet is already unlocked will set a new unlock
time that overrides the old one.


Unlock the wallet for 60 seconds
> bitcoin-cli walletpassphrase "my pass phrase" 60

Lock the wallet again (before 60 seconds)
> bitcoin-cli walletlock
