Locking litecoin wallet with JSON-RPC There is this very helpful post detailing how to lock and unlock your bitcoin wallet using walletlock and walletpassphrase api calls. Unfortunately the litecoin api does not boast these features. 

I was wondering if there is a similar strategy in place for securing a litecoin wallet perhaps using the lockunspent command?
Actually, Litecoin-Qt/litecoind v0.8.5.2 and probably several v0.8 releases before do support these api calls. 

The --help doesn't seem to have any entries on these commands but this is true of Bitcoin-Qt/bitcoind as well so if you want to submit a bug report or code it and submit a pull request, please do so at https://github.com/bitcoin/bitcoin.
