walletlock
Removes the wallet encryption key from memory, locking the wallet. After calling this method, you will need to call walletpassphrase again before being able to call any methods which require the wallet to be unlocked.
Examples
Set the passphrase for 2 minutes to perform a transaction
bitcoin-cli walletpassphrase "my pass phrase" 120
Perform a send (requires passphrase set)
bitcoin-cli sendtoaddress "1M72Sfpbz1BPpXFHz9m3CdqATR44Jvaydd" 1.0
Clear the passphrase since we are done before 2 minutes is up
bitcoin-cli walletlock
