What is JSON Web Token, and how it works for API authentication? ๐
A JSON-based open standard called JSON Web Token (JWT) is used to create access tokens that make a number of claims.
When using JWT authentication, a token is generated, signed by the server, and sent to the client.

The client then provides this token to the server with each subsequent request to demonstrate user authentication.

Letโs get our series started in which we make our case against token-based AuthZ.
JWTs are like a key and composed of three parts: a header, a payload, and a signature.
JWTs are like a key and composed of three parts: a header, a payload, and a signature.
The payload contains information to identify the owner of the token: user ID, email address, etc.
These are called claims and essentially, they can hold whatever info you may need.
These are called claims and essentially, they can hold whatever info you may need.
The signature is what makes a JWT secure, but JWTs are usually not encrypted.
The information is encoded (not encrypted), which means it can be decoded.
The way to keep JWTs secure is to make sure they are hashed using a secret.

A JSON Web Token, or JWT, is a type of authentication token that is used to identify a user.
It is a JSON object that contains a set of claims, or assertions, about the user.
These claims can be verified by a third party, such as a website or an application.

These claims can be verified by a third party, such as a website or an application.
This information can be verified and trusted because it is digitally signed.
A JWT can also be encrypted so that only the intended recipient can read the contents of the token.

Another new idea for #PenetrationTesting and #Bug-hunting:
Tester:
Enhance the force of #vulnerabilities by doing things like
I discovered a free #URL that leads somewhere else.
Put this in my report and move on ?

To the contrary, changing the #payload allowed me to transform it into a reflected #XSS #vulnerability. Is this the final question?
Obviously not if I have any hope of carrying on.

Our partners are now able to create and manage did:cheqd DIDs more easily, and for the first time on cheqd issue and verify #VerifiableCredentials (VCs) and Verifiable Presentation (VPs).

Having a readily available and transferable set of tools will help speed up adoption!
We knew our partners were eager to know โwhen will I be able to use the cheqd ledger for identity?โ and now weโre happy to say โgo have a play right now!โ. ๐ฅ

Following our research earlier in the year, we explored the development frameworks that our #SSI partners planned to utilise in future. The purpose of it was to determine a suitable toolset for our frens to get building on our network.

If you work with APIs, you've probably come across JWTs. JWT stands for ๐๐๐๐ ๐๐๐ ๐๐จ๐ค๐๐ง, and it's a JSON document that contains information about a user. We call the properties of a JWT claims.

There're two types of JWTs:
๐ ๐๐ ๐ญ๐จ๐ค๐๐ง๐ฌ are tokens carrying user-identifying data like their name and email. You should ๐๐๐๐๐ use an ID token to validate access to an API.
๐ ๐๐๐๐๐ฌ๐ฌ ๐ญ๐จ๐ค๐๐ง๐ฌ are tokens with claims about the right to access an API.

A JWT token (JSON Web Token) is just a string with a well-defined format. A sample token might look like this:
```
eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJoZWxsbyI6ImZyb20gSldUIn0.XoByFQCJvii_iOTO4xlz23zXmb4yuzC3gqrWNt3EHrg

```
There are 3 parts separated by a `.` (dot) character:
- header: eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9
- body: eyJoZWxsbyI6ImZyb20gSldUIn0
- signature: XoByFQCJvii_iOTO4xlz23zXmb4yuzC3gqrWNt3EHrg
- header: eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9
