This means fewer code-duplication. Also added another test for fromScript to
make sure it is thoroughly tested. Also pass through opts to createMultisig so
that you can choose to lot let it be sorted if you want.
To create an address from a public key or script, you used to have to do the
hashing yourself, and find the version yourself. For example:
var hash = bitcore.util.sha256ripe160(pubkey);
var version = bitcore.networks['livenet'].addressVersion;
var addr = new Address(version, hash);
But with this interface, things are much simpler:
var addr = Address.fromPubKey(pubkey);
The new convenience methods are:
Address.fromPubKey (for regular pubkeyhash addresses)
Address.fromPubKeys (for p2sh multisig addresses)
Address.fromScript (for any p2sh address)
The addUncompressed function is for node-only, and is a temporary workaround
until we expose a better crypto interface in both node and the browser. I wrote
tests for this function that were node-only, but were broken in the browser. I
also wrote tests for the Point class that should have worked in both node and
the browser, and did, but I was using the wrong module such that it worked only
in node. This update makes the tests work in the browser by using the correct
module.
The way I was outputting the pubkeys would be incorrect if the first byte of
one of the coordinates was 0, since it would print the first non-zero byte
first. The solution was to use the standard openssl function that outputs a
public key to oct.
BIP32 needs to be able to add two points on the secp256k1 curve. This
functionality was not already being exposed from OpenSSL in bitcore. I have
added an "addUncompressed" function to the Key class which takes in two points
in uncompressed form, adds them, and returns the result. This is necessary for
BIP32.
Added the ability to create a new master bip32 with new private key and chain code. The way this works is like this:
var bip32 = new BIP32('mainnet');
or:
var bip32 = new BIP32('testnet');
