const pbkdf2 = getPbkdf2OSha512({
  // generate random 64-byte long salt string, base64-encoded (default)
  iterations: 8192, // min 8192 (unless `relaxed`), default 65536
  length: 32 // min 32, max 64, default 64
  // digest is always 'sha512'
  // relaxed defaults to false
})
 
const rawpbkdf2 = getPbkdf2OSha512({
  encoding: 'none',
  iterations: 8192,
  length: 32
})
