* crypter: shuffle Makefile so that crypto can be used by the walletCory Fields2016-05-131-32/+23
| | | | | | | Wallet must come before crypto, otherwise linking fails on some platforms. Includes a tangentially-related general cleanup rather than making the Makefile sloppier.
* crypter: add a BytesToKey clone to replace the use of opensslCory Fields2016-05-132-4/+31
| | | | | BytesToKeySHA512AES should be functionally identical to EVP_BytesToKey, but drops the dependency on openssl.

* crypter: fix the stored initialization vector sizeCory Fields2016-05-132-6/+7
| | | | | | AES IV's are 16bytes, not 32. This was harmless but confusing. Add WALLET_CRYPTO_IV_SIZE to make its usage explicit.

* crypto: add AES 128/256 CBC classesCory Fields2016-05-132-0/+196
| | | | | | The output should always match openssl's, even for failed operations. Even for a decrypt with broken padding, the output is always deterministic (and attemtps to be constant-time).

| | | | | | | | | | | | | | | | | | | | Move the version reporting to Wallet::Verify, before starting verification of the wallet. This removes the dependency of init on a specific wallet database library. A further, trivial step towards resolving #7965.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I made a subclass of QMessageBox that disables the send button in exec() and starts a timer that calls a slot to re-enable it after a configurable delay. It also has a countdown in the send/yes button while it is disabled to hint to the user why the send button is disabled (and that it is actually supposed to be disabled).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch changes the implementation from one that stores 16 2-bit integers in one uint32_t's, to one that stores the first bit of 64 2-bit integers in one uint64_t and the second bit in another. This allows for 450x faster refreshing and 2.2x faster average speed.

I think this makes sense, as the other block-file stuff is there too. - Moving `CDiskTxPos` from `main.h` to `txdb.h`. This type seems specific to txdb. - Pass a functor `insertBlockIndex` to `LoadBlockIndexGuts`. This leaves it up to the caller how to insert block indices.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This will avoid sending more pointless INVs around updates, and prevents using filter updates to timetag transactions. Also adds locking for fRelayTxes.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | By eliminating queued entries from the mempool response and responding only at trickle time, this makes the mempool no longer leak transaction arrival order information (as the mempool itself is also sorted)-- at least no more than relay itself leaks it.

This causes high overhead because it makes >80% of INVs size 1. Doing so harms privacy, because it limits the amount of source obscurity a transaction can receive. These randomized broadcasts also disobeyed transaction dependencies and required use of the orphan pool. Because the orphan pool is so small this leads to poor propagation for dependent transactions. When the bypass wasn't in effect, transactions were sent in the order they were received. This avoided creating orphans but undermines privacy fairly significantly. This commit: Eliminates the bypass. The bypass is replaced by halving the average delay for outbound peers. Sorts candidate transactions for INV by their topological depth then by their feerate (then hash); removing the information leakage and providing priority service to higher fee transactions. Limits the amount of transactions sent in a single INV to 7tx/sec (and twice that for outbound); this limits the harm of low fee transaction floods, gives faster relay service to higher fee transactions. The 7 sounds lower than it really is because received advertisements need not be sent, and because the aggregate rate is multipled by the number of peers.
