In the CodeB Credential Provider Store, especially when using the Kerberos Connector, certificates are safeguarded in the local CodeB Certificate store with robust security measures. This store employs double encryption for enhanced protection. The first layer is AES encryption, which uses a dynamically generated machine-specific password. Additionally, the store is encrypted with the Microsoft Data Protection API (DPAPI), linking the encryption to the specific machine and ensuring decryption can only occur on the original machine.

Moreover, for heightened security, each key can be assigned a second factor of authentication. This can include options like an NFC card, TOTP (Time-based One-Time Password), and other similar methods. These added layers of security ensure that even if the file were to be stolen, the AES encryption could not be brute-forced on any other machine, and unauthorized access would be further hindered by the requirement of a second authentication factor.
