Creates a message to be signed from challenge data components

This function creates a canonical representation of the challenge data for signing. It takes individual challenge components rather than a complete challenge object, allowing it to be used during challenge creation.

Arguments

• random_nonce: The random nonce string
• created_time: The challenge creation timestamp
• expiration_time: The challenge expiration timestamp
• website_id: The website identifier
• challenge_param: The challenge parameter bytes
• public_key: The public key bytes

Returns

• String: Canonical string representation for signing
