# Class: GeneralEncrypt

The GeneralEncrypt class is a utility for creating General JWE objects.

**`example`** Usage
```js
const jwe = await new jose.GeneralEncrypt(
  new TextEncoder().encode(
    'It’s a dangerous business, Frodo, going out your door.'
  )
)
  .setProtectedHeader({ enc: 'A256GCM' })
  .addRecipient(ecPublicKey)
  .setUnprotectedHeader({ alg: 'ECDH-ES+A256KW' })
  .addRecipient(rsaPublicKey)
  .setUnprotectedHeader({ alg: 'RSA-OAEP-384' })
  .encrypt()

console.log(jwe)
```
