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));
     }
