Question - In Postman, what is digest auth?
Answer -
Postman provides the Digest Authorisation method as one of its authorization options. The client sends the request to the API first, and the server responds with a number that can only be used once a realm value and a 401 unauthorised response code. After that, we'll receive an encrypted data array including both the username and password and the previously obtained data from the server. The server generates an encrypted data string from this information and compares it to what was sent to authenticate the request.
This can be done by going to the Authorization tab and selecting "Digest Auth" from the drop-down menu. The fields for both stages of the authentication request are displayed in the Postman window. Based on the data received from the server, the fields required for the second step of the request are auto-filled.
