JWT

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

%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.

"<base64url-header>.<base64url-payload>.<base64url-signature>"

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

%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.

"<base64url-header>.<base64url-payload>.<base64url-signature>"
