* accounts, core, crypto, internal: use normalised V during signature handling ↵Péter Szilágyi2017-01-051-26/+5
| | | | | | | | | (#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-vk2016-10-291-4/+33
| | | | | | | | | | | | | | | | | | | | 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.

* accounts, crypto: move keystore to package accountsFelix Lange2016-04-121-106/+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.
