Adds asserts to ensure only valid hashes are created (until the
implementation is complete).
Also uses `Script.without` to remove OP_CODESEPARATOR from the Scripts
as required by the protocol.
Also fixes the bug when the sequence number is 0 and
`TransactionIn.defaultSequence` is used; resulting in an undefined
sequence number as it is undefined.
All the `invalid2` tests have been removed as they were not invalid
base58check. They were actually valid in some cases.
They will be re-integrated in more specific bitcoin core tests in
relation to Address/ECKey respectively.
By removing Address.Error, we remove a code smell.
This part of the code base was also not under any form of test.
Test data and tests have therefore been added verifying its behaviour in
both Wallet and Address tests.
This also adds tests for all other ECDSA serialize/parsing functions.
The k, r, s and D values were sourced from test vectors on
https://bitcointalk.org/index.php?topic=285142.40 .
The compact signatures (aka, i values) were generated from bitcoinjslib, but they
are straight forward anyway.
An ECKey is a composition of a private key (D), a public key (Q) and its
compression flag.
These functions gave the impression of serialization of this
composition, when really they only serialized `D`.
They have therefore been removed in favour of always using a sane
serialization format (WIF) that matches the needed behaviour.
If a user needs the previous functionality, simply use `privKey.D.*`
instead of `privKey.*`, as BigInteger supports `*Buffer/*Hex` functions
as expected.
