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 sign = function(hash: Buffer, privateKey: Buffer): string {
const signature = secp256k1.keyFromPrivate(privateKey).sign(hash, { canonical: true });
return "0x" + Buffer.concat([signature.r.toBuffer(), signature.s.toBuffer(), Buffer.from([signature.recoveryParam])]).toString("hex"); /* tslint:disable:max-line-length */
};示例3: getHexFromBN
const results = evilHexes.map((hex) => {
const ephemeralSK = ecurve.keyFromPrivate(hex)
const ephemeralPK = ephemeralSK.getPublic()
const sharedSecret = ephemeralSK.derive(ephemeralPK)
return getHexFromBN(sharedSecret).length === 64
})
