Flattened JWS JSON Serialization Syntax token. Payload is returned as an empty string when JWS
Unencoded Payload ([RFC7797](https://www.rfc-editor.org/info/rfc7797/)) is used.

## Properties

### payload

• **payload**: `string`

The "payload" member MUST be present and contain the value BASE64URL(JWS Payload). When RFC7797
"b64": false is used the value passed may also be a [Uint8Array](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/Uint8Array).

• **signature**: `string`

The "signature" member MUST be present and contain the value BASE64URL(JWS Signature).

Unprotected Header value is non- empty; otherwise, it MUST be absent. This value is represented
as an unencoded JSON object, rather than as a string. These Header Parameter values are not
integrity protected.

The "protected" member MUST be present and contain the value BASE64URL(UTF8(JWS Protected
Header)) when the JWS Protected Header value is non-empty; otherwise, it MUST be absent. These
