调用: web3.eth.sign(address, dataToSign, [, callback]) 参数: address: String - 签名使用的地址 dataToSign: String...示例: var result = web3.eth.sign("0x135a7de83802408321b74c322f8558db1679ac20", "0x9dd2c369a187b4e6b9c402f030e50743e619301ea62aa4c0737d4ef7e10a3d49
javascript表达如下: var msg = '0x8CbaC5e4d803bE2A3A5cd3DbE7174504c6DD0c1C' var hash = web3.sha3(msg) var sig = web3
('Hello world'); // sign only takes hexstrings, so turn message to hexstring const signedMessage = web3
result := mload(add(source, 32)) } } } 函数decode()传入经过签名后的数据,用于验证返回地址是否是之前用于签名的私钥对应的公钥地址,以太坊提供了web3...localhost:8545")); var account = web3.eth.accounts[0]; var sha3Msg = web3.sha3("abc"); var signedData = web3
原理是椭圆曲线加密算法,相关函数为 web3.eth.sign(address, dataToSign)、ecRecover,具体用法可以搜索下。
eth.getTransactionReceipt web3.eth.getTransactionCount web3.eth.sendTransaction web3.eth.sendRawTransaction web3...console.log(hash); // "0x7f9fade1c0d57a7af66ab4ead79fade1c0d57a7af66ab4ead7c2c2eb7b11a91385" }); web3....eth.sign web3.eth.sign(address, dataToSign, [, callback]) 使用指定帐户签名要发送的数据,帐户需要处于unlocked状态。...示例: var result = web3.eth.sign("0x135a7de83802408321b74c322f8558db1679ac20", "0x9dd2c369a187b4e6b9c402f030e50743e619301ea62aa4c0737d4ef7e10a3d49
