Retrieve the current business public key and its signature verification status.

This endpoint returns the public key that is currently configured for encrypting message payloads and indicates whether the stored signature is valid or has a mismatch.

Use Cases:

• Verify current encryption configuration
• Check public key signature validation status
• Retrieve public key for client-side encryption setup
• Monitor encryption key status for security compliance

Rate Limiting: Standard Graph API rate limits apply. Use appropriate retry logic with exponential backoff.

Caching: Public key information can be cached for moderate periods, but signature status may change and should be checked regularly for security validation.
