e192f9030c Prevent marriage of used keychain 
addFollowingAccounts method now has the check that active keychain has no keys in use. This would prevent divergence of derivation paths for followed and following keys. In future this behaviour should be replaced with some sort of key rotation.

e8048cb672 Changes to the Coin class: some convenience comparison operators; 
`parseCoin()` now accepts negative values; the check for an excessive
value is moved to the constructor from `parseCoin()` and uses
`checkArgument()`; some `Coin`-type constants broken out into one
`long` one `Coin` in order to be usable in the constructor.
Corresponding tests included.  The `BitcoinURI` class constructor
throws exception on parsing a negative amount, which is needed now
that `Coin` class accepts negative amounts.

3dfaf54e28 Fixed VarInt serialization bug for the 0xffffffff number. Fixed VarInt sizeOf bug for the 0xffffffff number and added tests for VarInt edge cases. 
The 4294967295 number (0xffffffff) was incorrectly serialized because the UnsignedInteger.MAX_VALUE.longValue() helper returned 4294967295 instead of expected 4294967296.

The VarInt.sizeOf() incorrectly returned 9 instead of 5 for the 4294967295 (0xffffffff) number.

292a180926 Full mode test generator: use OP_NOP in inputs instead of OP_TRUE to avoid unclean stacks after execution. Additionally, reduce the verbosity of the code somewhat. There's still plenty that could be done to make the code cleaner but .... not today. 2014-06-18 12:21:54 +02:00

9d1b15612a Fix a bug because the SendRequest.fee field is written to 0 when SendRequest.emptyWallet is used. Missing tests for this case are added. 
Use SendRequest.tx.getFee() to get the fee, rather than reading SendRequest.fee.

2a8454a85c HD wallet: currentKey is now stable after serialization roundtrip 
At the moment currentKeys map of KeyChainGroup is not restored after
deserialization and subsequent call to currentKey produces different
key then expected.
Proposed solution reconstructs currentKey map on deserialization using
stored numbers of issues keys. It is
not future-proof as it assumes only RECEIVE and CHANGE keys are being
used.

9f25af54ab Fixed bitcoinj DoS. It could have been crashed by a malicious message. 
Bitcoinj can be crashed with OutOfMemory by sending a message with
a large claimed var_str length or bytes array length.

The actual message size does not matter, it's the claimed length that matters.

This affects all bitcoinj-based apps that receive messages including Multibit, Android Bitcoin Wallet, Mycelium and Hive.

The fix limits accepted length to max message size (32 MB).

b374ba5108 HDW: Fix a decryption bug where we were (again) accidentally relying on padding checks to detect wrong passwords. Check the watching key derives correctly to fix. 2014-05-29 20:11:16 +02:00

24e41f01c6 Refactorings. 
Make a convenience ECKey.decrypt(KeyParameter) that doesn't require the keycrypter to be manually specified, as often (always?) the key knows it already.

Introduce a KeyBag interface that just contains findKeyBy* methods, then make Wallet implement it and change Transaction.signInputs to use it. Take out the encrypted-key specific stuff here: Transaction now requires unencrypted keys. Create a DecryptingKeyBag class that just forwards calls to Wallet and decrypts the returned keys. This decouples the signing code from Wallet a bit.

Should be all API compatible.

a807994b9a Bump wallet version and add missing check (!) to detect wallets from the future. The absence/incompleteness of this feature had not been noticed before, and it means that old apps will fail to read HD wallets due to the new key enum value rather than a more sensible error (but there's still no chance of an old app accepting an HD wallet, so it should still be safe). 2014-05-29 20:11:15 +02:00
