# PersonalDataNode

The cipher of `PersonalData` on `node:crypto`. WebCrypto, the default, is asynchronous, which makes each personal field cost a trip through the event loop. This one encrypts and decrypts synchronously, in the same format, so data written with either reads with the other.

```ts
const Keys = PersonalData.layerSql().pipe(
  Layer.provide(PersonalData.layerMasterKeyConfig()),
  Layer.provide(PersonalDataNode.layerCipher)
)
```

It lives in a module of its own so that code for browsers never imports `node:crypto`.
