How is HTTP basic authentication implemented in RESTAPI?

• A. Using query parameters
• B. Through the HTTP body
• C. Via HTTP headers
• D. By URL encoding credentials

Answer: (C)

HTTP basic authentication is implemented through HTTP headers. This method involves sending the user's credentials (username and password) in the Authorization header of the HTTP request. The credentials are encoded in Base64 format, following the scheme `Authorization: Basic <Base64 encoded credentials>`. Using HTTP headers for authentication helps separate the authentication process from the request body or URL, keeping sensitive information out of logs and URL histories where it could be exposed. Additionally, using query parameters or sending the credentials in the HTTP body can pose security risks, such as exposing sensitive information in logs or being susceptible to interception. URL encoding credentials would also not align with the standards established for basic authentication, which specifically designates the Authorization header for transmitting credentials securely. Thus, the use of HTTP headers stands as the correct and secure method for implementing HTTP basic authentication in REST APIs.
