## JWT(header: Object, payload: Object, signingKey: String, algorithm: String): String
Generate JWT with header, payload, and signature by specific algorithm.
_Introduced in DataWeave version 2.6.0._
### Parameters
Name
Type
Description
header
Object
JWT header.
payload
Object
JWT payload.
signingKey
String
RSA private key in PEM format.
algorithm
String
RSA algorithm, such as Sha384withRSA.
### Example
Supply `key` as a JSON string containing an unencrypted RSA private key with a modulus of at least
2048 bits. This example signs with RS384.
#### Source
```DataWeave
%dw 2.0
import * from dw::util::jwt::RSA
output application/json
input key application/json
---
JWT({kid: "example"}, {sub: "test"}, key, "Sha384withRSA")
```
#### Output
The exact signature depends on `key`.
```Json
".."
```
## JWT(payload: Object, signingKey: String): String
Generate JWT with a payload, automatically generated header, and key signed with RS256.
_Introduced in DataWeave version 2.6.0._
### Parameters
Name
Type
Description
payload
Object
JWT payload.
signingKey
String
RSA private key in PEM format.
### Example
Supply `key` as a JSON string containing an unencrypted RSA private key with a modulus of at least
2048 bits. This example signs with RS256.
#### Source
```DataWeave
%dw 2.0
import * from dw::util::jwt::RSA
output application/json
input key application/json
---
JWT({sub: "test"}, key)
```
#### Output
The exact signature depends on `key`.
```Json
".."
```
