Help users avoid insecure configurations a bit by recommending a
secure RPC password and increasing the incorrect password delay.
This may open up a RPC DOS for users with exposed RPC ports and
short passwords. Since users shouldn't have exposed RPC ports OR
short passwords, the DOS risk is preferable to the compromise
risk.
Also logs the client IP address for incorrect attempts.
base58-encoding of full/compressed public keys needs more thought; it probably makes sense to define a base58 encoding that includes a version byte and a checksum. So just support hex and bitcoin-address encodings for now.
This turns on most gcc warnings, and removes some unused variables and other code that triggers warnings.
Exceptions are:
-Wno-sign-compare : triggered by lots of comparisons of signed integer to foo.size(), which is unsigned.
-Wno-char-subscripts : triggered by the convert-to-hex functions (I may fix this in a future commit).
This patch enabled compressed pubkeys when -compressedpubkeys is passed.
These are 33 bytes instead of 65, and require only marginally more CPU
power when verifying. Compressed pubkeys have a different corresponding
address, so it is determined at generation. When -compressedpubkeys is
given, all newly generated addresses will use a compressed key, while
older/other addresses keep using normal keys. Unpatched clients will
relay and verify these transactions.
so it takes a flag for how to interpret OP_EVAL.
Also increased IsStandard size of scriptSigs to 500 bytes, so
a 3-of-3 multisig transaction IsStandard.
OP_EVAL is a new opcode that evaluates an item on the stack as a script.
It enables a new type of bitcoin address that needs an arbitrarily
complex script to redeem.
Introduces two new RPC calls:
* dumpprivkey: retrieve the private key corresponding to an address
* importprivkey: add a private key to your wallet
The private key format is analoguous to the address format. It is
a 51-character base58-encoded string, that includes a version number
and a checksum.
Includes patch by mhanne:
* add optional account parameter for importprivkey, if omitted use default
SecureString is identical to std::string except with secure_allocator
substituting for std::allocator. This makes casting between them
impossible, so converting between the two at API boundaries requires
calling ::c_str() for now.
This leads to the bitcoin core being shut down while the UI is accessing it, and generally results in a segmentation fault or crash. In case it is desirable to make it possible to shutdown the GUI from its RPC server, we'll need to implement a signal for it. For the mean time, this is a safe stopgap.
This RPC is exactly identical to getblockcount. This duplication
dates back to commit 22f721dbf2 when
Satoshi created the RPC interface.
There's no need to have both, so we standardize on "count" which
matches the naming convention in getconnectioncount.
Following the tradition established with previously deprecated APIs,
getblocknumber continues to work, but it's not listed in the help
system.
getmemorypool [data]
If [data] is not specified, returns data needed to construct a block to work on:
"version" : block version
"previousblockhash" : hash of current highest block
"transactions" : contents of non-coinbase transactions that should be included in the next block
"coinbasevalue" : maximum allowable input to coinbase transaction, including the generation award and transaction fees
"time" : timestamp appropriate for next block
"bits" : compressed target of next block
If [data] is specified, tries to solve the block and returns true if it was successful.
Instead of encoding the public key inside the signature string, use
key recovery to do verification. This allows 88-character base64-encoded
signature strings instead of 188-character ones.
This replaces the openssl-based base64 encoder and decoder with a more
efficient internal one. Tested against the rfc4648 test vectors.
Decoder is based on JoelKatz' version.
