我就让它写一个加密，我干出来这个 
function deriveKey(password: string, salt: Buffer): Buffer {
  return scryptSync(password, salt, KEY_LENGTH);
}
function scryptSync(password: string, salt: Buffer, keylen: number): Buffer {
  return scrypt(password, salt, keylen, { N: 16384, r: 8, p: 1 }, () => {}) as Buffer;
}

不是，它都不知道它在上面写了 
import { randomBytes, createCipheriv, createDecipheriv, scryptSync } from 'crypto';

吗...
