* 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
