brollet's Issues

When displaying fee, allow user to quit transaction.

Replace the current alertbox with an option that 'breaks' the transaction. In case the fee is incorrect (maybe too high).

Move 'Before Balance' into the top-bar navigation.

Add an about page.

This should link to the github project and the bitcoin thread.

Implement multisig transactions.

Implement multisig transactions and then integrate into email transactions.

Keys into ECKey

Currently the Keys variable holds private keys in hex format. The following is how to convert hex keys into ECKey.

var hexKey = Keys[..btcaddy..];
var bigIntKey = new BigInteger(hexKey, 16);
bigIntKey = bigIntKey.mod(getSECCurveByName("secp256k1").getN())
var eckey = new ECKey(bigIntKey)

Here is an example of converting a hex private key into a base58 bitcoin address

var eckey = ..follow.. steps above
var pub = eckey.getPub()
var pubkeyHash = Bitcoin.Util.sha256ripe160(pub)
var btcAddress = new Bitcoin.Address(pubkeyHash)

Wrap 'Keys' in Object that implements Map and List interfaces.

For example,
keys[0] returns the first key
and
keys[..base58address..] returns corresponding key
