Jwt

Jwt is a PowerShell module for creating and verifying JSON Web Tokens. This repository maintains the current Jwt module command surface under PSModule maintenance so existing users can continue to install and use the package from PowerShell Gallery.

Installation

Install-PSResource -Name Jwt
Import-Module -Name Jwt

Commands

The maintained module exports the same JWT commands and alias used by the current package:

ConvertFrom-Base64UrlString
ConvertTo-Base64UrlString
Get-JwtHeader
Get-JwtPayload
New-Jwt
Test-Jwt
Verify-JwtSignature

Usage

Create and validate an HMAC-signed JWT:

$header = '{"alg":"HS256","typ":"JWT"}'
$payload = '{"sub":"1234567890","name":"John Doe","admin":true,"iat":1516239022}'
$secret = 'a-string-secret-at-least-256-bits-long'

$jwt = New-Jwt -Header $header -PayloadJson $payload -Secret $secret
Test-Jwt -jwt $jwt -Secret $secret

Read the header and payload from an existing token:

Get-JwtHeader -jwt $jwt
Get-JwtPayload -jwt $jwt

For more information about each command, use PowerShell help:

Get-Command -Module Jwt
Get-Help New-Jwt -Full
