示例1: constructor
/**
* Passing an external key will import it, otherwise a keypair will
* be generated.
*/
constructor(ext?: string) {
if (ext) {
const keyParts = ext.split("|");
const d = Base64.decode(keyParts[2]);
this.keyPair = elliptic.keyFromPrivate(Buffer.from(d));
} else {
// Generate our own key since we have a good PRNG
const d = new Uint8Array(32);
crypto.getRandomValues(d);
this.keyPair = elliptic.keyFromPrivate(Buffer.from(d));
}
}示例2: function
export const recover = function(hash: Buffer, sig: Buffer): string {
const recovery = sig[64];
const signature = {
r: sig.slice(0, 32),
s: sig.slice(32, 64),
};
const ecPublicKey = secp256k1.recoverPubKey(hash, signature, recovery);
const publicKey = "0x" + ecPublicKey.encode("hex", false).slice(2);
const publicHash = EthLib.hash.keccak256(publicKey);
const address = EthLib.account.toChecksum("0x" + publicHash.slice(-40));
return address;
};示例3: addressFromPublicKeyBuffer

const ecKey = secp.keyFromPublic(pubKey);
const x = ecKey
.getPublic()
.getX()
.toBuffer();
const y = ecKey

const paddedBuffer = Buffer.concat([this.padTo32(x), this.padTo32(y)]);
