FAQ-000701 - Data Storage and Encryption Security / Encryption and Key Management

Using the Salesforce Crypto class for encryption can help in passing the security review for API key storage, as long as the encryption is implemented correctly and securely. It's recommended to store sensitive data, like API keys, in protected custom settings or encrypted fields, and ensure that encryption keys are managed securely. For API integrations, consider using Named Credentials instead of storing API keys directly, as this provides better security and key management.

The existing answer is technically sound but could be enhanced to provide more comprehensive guidance on API key security. The main improvement is adding guidance about Named Credentials as a preferred alternative to storing API keys directly, which aligns with Salesforce best practices for external integrations. This addition provides users with the most secure approach while maintaining all the existing information about encryption.
