bakd247, thank you for your reply, but, with all due respect, according to Litecoin API this is not true what you say. According to API the first number is the passphrase (not for how many seconds you want your wallet unlocked). My question is as follows:
I've got spaces at the beginning and the end of the passphrase, which is (let's assume) space100space200space300space. I want my wallet unlocked for 400 seconds. What command should I send via litecoin-cli?
./litecoin-cliSPACEwalletpassphraseSPACESPACE100SPACE200SPACE300SPACESPACE400 ? Is that a correct command? Thank you.
