HTTP API Client Authenticator

Build a simple HTTP API client authentication module that handles user credentials and generates proper authorization headers for API requests.

Requirements

Authentication Header Generation

Your module should provide functionality to prepare authentication headers for HTTP requests to various APIs. The system needs to:

• Accept user credentials (username and password)
• Generate properly formatted authentication headers suitable for HTTP Basic Authentication
• Support different character encodings for credentials (ASCII/Latin-1 and UTF-8)
• Return headers in a format ready to be added to HTTP requests

API Endpoints Support

The module should support authentication for two different API services:

Standard ASCII API

• Requires Basic Authentication
• Uses standard ASCII/Latin-1 encoding for credentials
• Returns authentication header as a dictionary with key "Authorization"

International API

• Requires Basic Authentication
• Supports international characters in usernames/passwords
• Uses UTF-8 encoding for credentials
• Returns authentication header as a dictionary with key "Authorization"

Test Cases

• When authenticating to the Standard ASCII API with username "admin" and password "secret123", the returned header dictionary should contain an "Authorization" key with the correct Basic Authentication value @test

• When authenticating to the International API with username "用户" (Chinese for "user") and password "пароль" (Russian for "password"), the returned header dictionary should contain an "Authorization" key with the correct UTF-8 encoded Basic Authentication value @test

• The authentication header values should be properly formatted according to HTTP Basic Authentication standards (Base64 encoded username:password combination) @test

    Returns:
        Dictionary containing the Authorization header
