From b59c8399fbe42390a3d41e945d03b1f21c1a9b8d Mon Sep 17 00:00:00 2001 From: bas-vk Date: Fri, 28 Oct 2016 21:25:49 +0200 Subject: internal/ethapi: add personal_sign and fix eth_sign to hash message (#2940) 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 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/abi/bind/auth.go | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'accounts/abi/bind') diff --git a/accounts/abi/bind/auth.go b/accounts/abi/bind/auth.go index 2cf22768c..cd6adc746 100644 --- a/accounts/abi/bind/auth.go +++ b/accounts/abi/bind/auth.go @@ -52,7 +52,7 @@ func NewKeyedTransactor(key *ecdsa.PrivateKey) *TransactOpts { if address != keyAddr { return nil, errors.New("not authorized to sign this account") } - signature, err := crypto.Sign(tx.SigHash().Bytes(), key) + signature, err := crypto.SignEthereum(tx.SigHash().Bytes(), key) if err != nil { return nil, err } -- cgit v1.2.3
