JSON Web Token

There was a time when the one and the only way to authenticate an individual only through the application that was by giving or providing the credentials. Later came to the service called API integration. This sends the credentials in plain text format and was unacceptable. The API tokens came into effect and these days, they are very, very common practice. Some of the benefits of giving out the credentials to an application as well as maintaining the user’s state in relation to the application with the session is cookies are:

Data Is Kept In Plain Text On The Server

Even you know that data are usually not kept in a general folder, anybody with access can read the content of the session files.

File System Read Or Write Request

Every time your session starts or its data is modified that way, the server needs to be updated the session file.

  • The data you have kept to be pay loaded of JWS that is JSON Web Signature.
  • The use of JWT has many benefits as well as advantages over the single API key.

The Json web signature is nothing but a cryptographic mechanism which is designed to secure the data with the digital signature that has a unique identity to the content of the token. This type of token has its uniqueness in such a way that we are capable determine or recognize if the data of the token has been tampered without or with it.
