Signatures

Use this section to define 0 or more custom claims for your token. The claim type can be anything, and so can the value. If recipient of the token is a.NET Framework application, you might want to follow the Microsoft ClaimType names. You can also use the.NET-oriented claim buttons below. Apr 26, 2019 Angular Security - Authentication With JSON Web Tokens (JWT): The Complete Guide Last Updated: 26 April 2019 localoffer Angular Security This post is a step-by-step guide for both designing and implementing JWT-based Authentication in an Angular Application.

JSON Web Signatures (JWS) can securecontent, such as text, JSON or binary data, with a digitalsignature (RSA, EC or EdDSA) or aHash-based Message Authentication Code(HMAC).

  1. While JWT and SAML tokens can also use a public/private key pair in the form of a X.509 certificate to sign them. However, signing XML with XML Digital Signature without introducing obscure security holes is very difficult compared to the simplicity of signing JSON.
  2. Oct 31, 2018 Uses the SECRETKEY static property to generate the signing key; Uses the fluent API to add the claims and sign the JWT; Sets the expiration date; This could be customized to your needs. If, for example, you wanted to add different or custom claims. Decode a Token. Now take a look at the even simpler decodeJWT method.
  3. Apr 12, 2015  We tried to make it very easy to both construct and verify JWTs using JSON Web Token for Java. You only need to specify the data you want to encode and sign it with a key. Later, with that same key you can verify the authenticity of the token and decode it. The benefits of using JWT greatly exceed the time and effort of implementing them.

Create / verify JWS examples with generic payload:

  • JWS with EdDSA / Ed25519 signature (RFC 8037)

JWS can also secure JSON Web Tokens (JWT):

  • JWT with ES256K signature (secp256k),used in Bitcoin and Ethereum
  • JWT with EdDSA / Ed25519 signature (RFC 8037)

Encryption

JSON Web Encryption (JWE) providesconfidentiality of content, while also ensuring its integrity. Public / private(RSA and EC) as well as symmetric encryption are supported.

Create / decrypt JWE examples:

Secure framework for processing JOSE and JWT objects

The library provides a powerful and secure framework for handling tokens andmessages secured with JOSE, such as JWT-based access tokens and OpenID tokens.The framework follows the security recommendations of the JOSE working groupand has been tried with a wide range of use cases.

Parsing JOSE and JWT objects

Parsing objects and tokens of a particular type (unsecured, JWS, JWE):

Parsing objects and tokens of any type (unsecured, JWS, JWE):

About JSON Web Tokens

JSON Web Tokens (JWTs) are an open standard for securely making claims.Identity is one example of a claim.Hence JWTs underpin one authentication approach used by Yodlee APIs.JWTs are a convenient alternative to SAML authentication used by large financial institutions.

Where to find more info on JWTs

The website jwt.io has an array of useful information.It has a debugger, allowing you to paste in a token and your key.It will decode it, or issue an error, allowing you to confirm that your code works.The site also has many open source libraries for token processing.

Yodlee Token Types

Yodlee JWTs come in two varieties: app tokens, and user tokens.You use one or the other depending on the specific Yodlee API.

App tokens have the 'issuer id' value from your developer dashboard.This identifies you, the app developer.

App tokens are only needed for Yodlee APIs that provide general information.

User tokens have all the same information as an app token, along with one extra field, a user id.The id represents the specific end user you are working with (i.e. your client).

User tokens are used for Yodlee APIs that return information regarding a particular end user.

In the developer portal, users are identified by 20-character unique strings that you (the developer) assign to keep track of your users.You can see a list of 5 predefined test users in your developer account dashboard.They have this general appearance: 'sbMem5c758c82bb1d12'.

Outside the developer portal, your app can use any scheme you find convenient to create and assign unique ids to your end users.They can be from 3 to 150 characters in length.

Read the documentation here for more information on using JWTs with Yodlee APIs.

About the Applications

This repositoriy includes sample programs showing how to work with JWTs in:

After you clone this repository, select the subdirectory that references your language of choice.

Each subdirectory has language-specific installation and usage instructions in the related README file.

Generate (JWT generation sample)

One set of samples included here show how to generate JWTs.See the code under the generate directories.

To generate a JWT, you need your issuer id and private key from yourdeveloper account dashboard.

Copy/paste your private key into a file.You’ll need to supply the file path to the application.The private key is given to you in PEM format, which uses a limitedset of ASCII characters, allowing easy copy/paste.

Keep your private key secret and do not share with others.Never put your private key into an app or on a mobile device.

All the applications require arguments, and the formats are very similar.

  • The -i or --issuer-id argument is required, and should reference your Issuer Id in the Yodlee Dashboard.

  • The -k or --key argument is required, and should reference the path to a copy of your private key in PEM format.

  • the -u or --username argument is optional, and should reference a valid username in your environment.

By passing in a --username argument, you will be generating a user token.Otherwise, you will be generating an app tokenSee Yodlee Token Types.

A typical invokation of one of the apps will look like

That version doesn’t include a username, so that will produce an application token.

That will produce a user token.
