`web3.eth.sendTransaction(object)` was modified to support private transactions

web3.eth.sendTransaction(transactionObject [, callback])

Sends a transaction to the network.

Parameters

Object - The transaction object to send:

from: String - The address for the sending account. Uses the web3.eth.defaultAccount property, if not specified.
to: String - (optional) The destination address of the message, left undefined for a contract-creation transaction.
value: Number|String|BigNumber - (optional) The value transferred for the transaction in Wei, also the endowment if it's a contract-creation transaction.
gas: Number|String|BigNumber - (optional, default: To-Be-Determined) The amount of gas to use for the transaction (unused gas is refunded).
~~gasPrice: Number|String|BigNumber - (optional, default: To-Be-Determined) The price of gas for this transaction in wei, defaults to the mean network gas price.~~
data: String - (optional) Either a byte string containing the associated data of the message, or in the case of a contract-creation transaction, the initialisation code.
nonce: Number - (optional) Integer of a nonce. This allows to overwrite your own pending transactions that use the same nonce.
privateFrom: String - (optional) When sending a private transaction, the sending party's base64-encoded public key to use. If not present and passing privateFor, use the default key as configured in the TransactionManager.
privateFor: List<String> - (optional) When sending a private transaction, an array of the recipients' base64-encoded public keys.

Function - (optional) If you pass a callback the HTTP request is made asynchronous. See this note for details.

Returns

String - The 32 Bytes transaction hash as HEX string.

If the transaction was a contract creation use web3.eth.getTransactionReceipt() to get the contract address, after the transaction was mined.

Example

// compiled solidity source code using https://chriseth.github.io/cpp-ethereum/
var code = "603d80600c6000396000f3007c01000000000000000000000000000000000000000000000000000000006000350463c6888fa18114602d57005b6007600435028060005260206000f3";

web3.eth.sendTransaction({
    data: code,
    privateFor: ["ROAZBWtSacxXQrOe3FGAqJDyJjFePR5ce4TSIzmJ0Bc="]
  },
  function(err, address) {
    if (!err) {
      console.log(address); // "0x7f9fade1c0d57a7af66ab4ead7c2eb7b11a91385"
    }
  }
