999e4c9 wallet: Change CCrypter to use vectors with secure allocator (Wladimir J. van der Laan)
* HD wallet
Minimal set of changes (no refactoring) backported from Bitcoin upstream to make HD wallets work in Dash 0.12.1.x+
* minimal bip44 (hardcoded account and change)
* minimal bip39
Additional cmd-line options for new wallet:
-mnemonic
-mnemonicpassphrase
* Do not recreate HD wallet on encryption
Adjusted keypool.py test
* Do not store any private keys for hd wallet besides the master one
Derive all keys on the fly.
Original idea/implementation - btc PR9298, backported and improved
* actually use bip39
* pbkdf2 test
* backport wallet-hd.py test
* Allow specifying hd seed, add dumphdseed rpc, fix bugs
- -hdseed cmd-line param to specify HD seed on wallet creation
- dumphdseed rpc to dump HD seed
- allow seed of any size
- fix dumpwallet rpc bug (wasn't decrypting HD seed)
- print HD seed and extended public masterkey on dumpwallet
* top up keypool on HD wallet encryption
* split HD chain: external/internal
* add missing cs_wallet lock in init.cpp
* fix `const char *` issues (use strings)
* default mnemonic passphrase is an empty string in all cases
* store mnemonic/mnemonicpassphrase
replace dumphdseed with dumphdinfo
* Add fCrypted flag to CHDChain
* prepare internal structures for multiple HD accounts
(plus some code cleanup)
* use secure allocator for storing sensitive HD data
* use secure strings for mnemonic(passphrase)
* small fix in GenerateNewHDChain
* use 24 words for mnemonic by default
* make sure mnemonic passphrase provided by user does not exceed 256 symbols
* more usage of secure allocators and memory_cleanse
* code cleanup
* rename: CSecureVector -> SecureVector
* add missing include
* fix warning in rpcdump.cpp
* refactor mnemonic_check (also fix a bug)
* move bip39 functions to CMnemonic
* Few fixes for CMnemonic:
- use `SecureVector` for data, bits, seed
- `Check` should return bool
* init vectors with desired size where possible
libsecp256k1's API changed, so update key.cpp to use it.
Libsecp256k1 now has explicit context objects, which makes it completely thread-safe.
In turn, keep an explicit context object in key.cpp, which is explicitly initialized
destroyed. This is not really pretty now, but it's more efficient than the static
initialized object in key.cpp (which made for example bitcoin-tx slow, as for most of
its calls, libsecp256k1 wasn't actually needed).
This also brings in the new blinding support in libsecp256k1. By passing in a random
seed, temporary variables during the elliptic curve computations are altered, in such
a way that if an attacker does not know the blind, observing the internal operations
leaks less information about the keys used. This was implemented by Greg Maxwell.
Add a sanity check to prevent cosmic rays from flipping a bit in the
generated public key, or bugs in the elliptic curve code. This is
simply done by signing a (randomized) message, and verifying the
result.
This allows for a reversal of the current behavior.
This:
CScript foo;
CScriptID bar(foo.GetID());
Becomes:
CScript foo;
CScriptID bar(foo);
This way, CScript is no longer dependent on CScriptID or Hash();
- ensures a consistent usage in header files
- also add a blank line after the copyright header where missing
- also remove orphan new-lines at the end of some files
Previously if bitcoind is linked with an OpenSSL which is compiled
without EC support, this is seen as an assertion failure "pKey !=
NULL" at key.cpp:134, which occurs after several seconds. It is an
esoteric piece of knowledge to interpret this as "oops, I linked
with the wrong OpenSSL", and because of the delay it may not even
be noticed.
The new output is
: OpenSSL appears to lack support for elliptic curve cryptography. For
more information, visit
https://en.bitcoin.it/wiki/OpenSSL_and_EC_Libraries
: Initialization sanity check failed. Bitcoin Core is shutting down.
which occurs immediately after attempted startup.
This also blocks in an InitSanityCheck() function which currently only
checks for EC support but should eventually do more. See #4081.
a81cd968 introduced a malleability breaker for signatures
(using an even value for S). In e0e14e43 this was changed to
the lower of two potential values, rather than the even one.
Only the signing code was changed though, the (for now unused)
verification code wasn't adapted.
Use misc methods of avoiding unnecesary header includes.
Replace int typedefs with int##_t from stdint.h.
Replace PRI64[xdu] with PRI[xdu]64 from inttypes.h.
Normalize QT_VERSION ifs where possible.
Resolve some indirect dependencies as direct ones.
Remove extern declarations from .cpp files.
Special serializers for script which detect common cases and encode
them much more efficiently. 3 special cases are defined:
* Pay to pubkey hash (encoded as 21 bytes)
* Pay to script hash (encoded as 21 bytes)
* Pay to pubkey starting with 0x02, 0x03 or 0x04 (encoded as 33 bytes)
Other scripts up to 121 bytes require 1 byte + script length. Above
that, scripts up to 16505 bytes require 2 bytes + script length.
This introduces internal types:
* CKeyID: reference (hash160) of a key
* CScriptID: reference (hash160) of a script
* CTxDestination: a boost::variant of the former two
CBitcoinAddress is retrofitted to be a Base58 encoding of a
CTxDestination. This allows all internal code to only use the
internal types, and only have RPC and GUI depend on the base58 code.
Furthermore, the header dependencies are a lot saner now. base58.h is
at the top (right below rpc and gui) instead of at the bottom. For the
rest: wallet -> script -> keystore -> key. Only keystore still requires
a forward declaration of CScript. Solving that would require splitting
script into two layers.
