Which two elements help to secure your API keys? (Choose two.)

Randomness is essential for generating strong, unpredictable API keys initially, but it is a property of the key's creation rather than an ongoing 'element' that actively secures an existing key in terms of its management or protection from compromise.

While SHA1 is a hashing algorithm and not direct encryption, it can be used in conjunction with API keys for cryptographic operations like HMAC-SHA1 to sign API requests, ensuring message integrity and authenticity and thus helping to secure the communication using the key.

Triple AES (Advanced Encryption Standard) is a strong symmetric encryption algorithm that would be excellent for securely storing API keys at rest; however, given the provided correct answers, the question likely seeks different types of security 'elements' or practices.

Rotation refers to the practice of regularly changing API keys. This is a critical security measure because it limits the window of opportunity for an attacker if a key is compromised, significantly reducing the impact of a breach.

A dictionary refers to a list of common words or patterns used in dictionary attacks, which are what strong, random keys and robust security practices aim to prevent, not an element that secures keys.
