It should be..


If you are using Geth, you should start it with personal api. geth --testnet --rpc --rpcport 8545 --rpcaddr --rpccorsdomain "*" --rpcapi "admin,db,debug,eth,miner,net,personal,shh,txpool,web3" console. Be careful with what you are going to expose otherwise you may make your node vulnerable for attacks. If it is for tests only, don´t worry, but if it is for production and you are dealing with serious amount of money, use it with a lot of careful.
