Cryptographic keys that protect access tokens must be protected.

Cryptographic keys are used to sign and verify access tokens, ensuring they have not been tampered with and that the user or service presenting the token is legitimate. If these keys are not securely managed, attackers could generate fraudulent tokens, bypass security controls, and gain unauthorized access to sensitive data or services. The API must protect these keys from disclosure or misuse, employing best practices such as key rotation, secure storage, and limiting access to only trusted entities. This minimizes the risk of key compromise, ensures tokens remain valid and trustworthy, and helps maintain the confidentiality and integrity of the authentication system.

By securing the cryptographic keys, the API mitigates the potential for security breaches and upholds a strong defense against various attack vectors.
