* crypto/secp256k1: unify the package license to 3-Clause BSD (#17225)Péter Szilágyi2018-07-245-60/+43
| | | | | | | | | | | | | | | | | | | | | | | | | | Our original wrapper code had two parts. One taken from a third party repository (who took it from upstream Go) licensed under BSD-3. The second written by Jeff, Felix and Gustav, licensed under LGPL. This made this package problematic to use from the outside. With the agreement of the original copyright holders, this commit changes the license of the LGPL portions of the code to BSD-3: --- I agree changing from LGPL to a BSD style license. Jeff --- Hey guys, My preference would be to relicense to GNUBL, but I'm also OK with BSD. Cheers, Gustav --- Felix Lange (fjl): I would approve anything that makes our licensing less complicated ---
* crypto: replace ToECDSAPub with error-checking func UnmarshalPubkey (#16932)Felix Lange2018-06-122-6/+38
| | | | | | ToECDSAPub was unsafe because it returned a non-nil key with nil X, Y in case of invalid input. This change replaces ToECDSAPub with UnmarshalPubkey across the codebase.

* crypto: add DecompressPubkey, VerifySignature (#15615)Felix Lange2017-12-066-15/+212
| | | | | | | We need those operations for p2p/enr. Also upgrade github.com/btcsuite/btcd/btcec to the latest version and improve BenchmarkSha3. The benchmark printed extra output that confused tools like benchstat and ignored N.
* crypto/bn256: fix generator on G1 (#15591)Matthew Di Ferrante2017-12-011-1/+1
| | | | | | | | | | | | | Generator in the current lib uses -2 as the y point when doing ScalarBaseMult, this makes it so that points/signatures generated from libs like py_ecc don't match/validate as pretty much all other libs (including libsnark) have (1, 2) as the standard generator. This does not affect consensus as the generator is never used in the VM, points are always explicitly defined and there is not ScalarBaseMult op - it only makes it so that doing "import github.com/ethereum/go-ethereum/crypto/bn256" doesn't generate bad points in userland tools.

* | consensus, core/*, params: metropolis preparation refactorJeffrey Wilcke2017-05-1811-0/+2538
|/ | | | | | | | | | | | | | | | | | | | | | | | This commit is a preparation for the upcoming metropolis hardfork. It prepares the state, core and vm packages such that integration with metropolis becomes less of a hassle. * Difficulty calculation requires header instead of individual parameters * statedb.StartRecord renamed to statedb.Prepare and added Finalise method required by metropolis, which removes unwanted accounts from the state (i.e. selfdestruct) * State keeps record of destructed objects (in addition to dirty objects) * core/vm pre-compiles may now return errors * core/vm pre-compiles gas check now take the full byte slice as argument instead of just the size * core/vm now keeps several hard-fork instruction tables instead of a single instruction table and removes the need for hard-fork checks in the instructions * core/vm contains a empty restruction function which is added in preparation of metropolis write-only mode operations * Adds the bn256 curve * Adds and sets the metropolis chain config block parameters (2^64-1)

This commit replaces them all with Int.Sign, which is cheaper and less code. eg templates: func before(x *big.Int) bool { return x.BitLen() == 0 } func after(x *big.Int) bool { return x.Sign() == 0 } func before(x *big.Int) bool { return x.BitLen() > 0 } func after(x *big.Int) bool { return x.Sign() != 0 } func before(x *big.Int) int { return x.Cmp(common.Big0) } func after(x *big.Int) int { return x.Sign() } * common/math, crypto/secp256k1: make ReadBits public in package math
* common: move big integer math to common/math (#3699)Felix Lange2017-02-271-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * common: remove CurrencyToString Move denomination values to params instead. * common: delete dead code * common: move big integer operations to common/math This commit consolidates all big integer operations into common/math and adds tests and documentation. There should be no change in semantics for BigPow, BigMin, BigMax, S256, U256, Exp and their behaviour is now locked in by tests. The BigD, BytesToBig and Bytes2Big functions don't provide additional value, all uses are replaced by new(big.Int).SetBytes(). BigToBytes is now called PaddedBigBytes, its minimum output size parameter is now specified as the number of bytes instead of bits. The single use of this function is in the EVM's MSTORE instruction. Big and String2Big are replaced by ParseBig, which is slightly stricter. It previously accepted leading zeros for hexadecimal inputs but treated decimal inputs as octal if a leading zero digit was present. ParseUint64 is used in places where String2Big was used to decode a uint64. The new functions MustParseBig and MustParseUint64 are now used in many places where parsing errors were previously ignored. * common: delete unused big integer variables * accounts/abi: replace uses of BytesToBig with use of encoding/binary * common: remove BytesToBig * common: remove Bytes2Big * common: remove BigTrue * cmd/utils: add BigFlag and use it for error-checked integer flags While here, remove environment variable processing for DirectoryFlag because we don't use it. * core: add missing error checks in genesis block parser * common: remove String2Big * cmd/evm: use utils.BigFlag * common/math: check for 256 bit overflow in ParseBig This is supposed to prevent silent overflow/truncation of values in the genesis block JSON. Without this check, a genesis block that set a balance larger than 256 bits would lead to weird behaviour in the VM. * cmd/utils: fixup import

* accounts, core, crypto, internal: use normalised V during signature handling ↵Péter Szilágyi2017-01-052-76/+29
| | | | | | | | | (#3455) To address increasing complexity in code that handles signatures, this PR discards all notion of "different" signature types at the library level. Both the crypto and accounts package is reduced to only be able to produce plain canonical secp256k1 signatures. This makes the crpyto APIs much cleaner, simpler and harder to abuse.
* internal/ethapi: add personal_sign and fix eth_sign to hash message (#2940)bas-vk2016-10-292-10/+62
| | | | | | | | | | | | | | | | | | | | This commit includes several API changes: - The behavior of eth_sign is changed. It now accepts an arbitrary message, prepends the well-known string \x19Ethereum Signed Message:\n<length of message> hashes the result using keccak256 and calculates the signature of the hash. This breaks backwards compatability! - personal_sign(hash, address [, password]) is added. It has the same semantics as eth_sign but also accepts a password. The private key used to sign the hash is temporarily unlocked in the scope of the request. - personal_recover(message, signature) is added and returns the address for the account that created a signature.
* crypto/sha3: update from golang.org/x/crypto/sha3 a 80b25ed4Felix Lange2016-10-026-3/+410

* accounts, crypto: move keystore to package accountsFelix Lange2016-04-129-1160/+0
| | | | | | | | | | The account management API was originally implemented as a thin layer around crypto.KeyStore, on the grounds that several kinds of key stores would be implemented later on. It turns out that this won't happen so KeyStore is a superflous abstraction. In this commit crypto.KeyStore and everything related to it moves to package accounts and is unexported.

* doc: crypto/secp256k1 GMP dependency package name.Noel Maersk2015-04-231-1/+4
| | | | | | | | | | | | | | Linux build documentation is mostly geared towards Ubuntu 14.04 (LTS). Appropriate package is called `libgmp-dev` there. Note that on pristine installations building `geth` with godep will fail because this header is missing. This is not documented in the top-level README, but is on the wiki: https://github.com/ethereum/go-ethereum/wiki/Installation-Instructions-for-Ubuntu#building-geth-command-line-client That page recommends `libgmp3-dev`, which ATM provides same version as `libgmp-dev`.
