Struct parity_crypto::publickey::ZeroesAllowedMessage

source · [−]

pub struct ZeroesAllowedMessage(pub H256);

Expand description

In ethereum we allow public key recovery from a signature + message pair where the message is all-zeroes. This conflicts with the best practise of not allowing such values and so in order to avoid breaking consensus we need this to work around it. The ZeroesAllowedType wraps an H256 that can be converted to a [u8; 32] which in turn can be cast to a secp256k1::Message by the ThirtyTwoByteHash and satisfy the API for recover().
