Felix Lange	0255951587	crypto: replace ToECDSAPub with error-checking func UnmarshalPubkey (#16932 ) 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.	7 years ago
kiel barry	ba975dc093	crypto: fix golint warnings (#16710 )	7 years ago
Felix Lange	1a32bdf92c	crypto: fix error check in toECDSA (#15632 ) With this change, key, err := crypto.HexToECDSA("000000...") returns nil key and an error instead of a non-nil key with nil X and Y inside. Issue found by @guidovranken.	7 years ago
Felix Lange	e85b68ef53	crypto: add DecompressPubkey, VerifySignature (#15615 ) 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.	7 years ago

Felix Lange	9b0af51386	crypto: add btcec fallback for sign/recover without cgo (#3680 ) * vendor: add github.com/btcsuite/btcd/btcec * crypto: add btcec fallback for sign/recover without cgo This commit adds a non-cgo fallback implementation of secp256k1 operations. * crypto, core/vm: remove wrappers for sha256, ripemd160	8 years ago
Felix Lange	e0ceeab0d1	crypto/secp256k1: update to github.com/bitcoin-core/secp256k1 @ 9d560f9 (#3544 ) - Use defined constants instead of hard-coding their integer value. - Allocate secp256k1 structs on the C stack instead of converting []byte - Remove dead code	8 years ago

Péter Szilágyi	08eea0f0e4	accounts, core, crypto, internal: use normalised V during signature handling (#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.	8 years ago
bas-vk	b59c8399fb	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<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.	8 years ago
