  • Enhanced cryptography systems and methods
    Patent number: 12719656
    Abstract: Methods and systems for extending white-box cryptography are provided. A computing device can maintain, in a memory, one or more cryptography keys encrypted using a white-box cryptography solution. The one or more cryptography keys encrypt or decrypt data with a cryptography algorithm not supported by the white-box cryptography solution. The computing device can perform one or more anti-tampering verifications to detect tampering events for tampering with the computing device or an application installed on the computing device. The computing device can, upon determining that no tampering event is detected, decrypt the one or more cryptography keys using the white-box cryptography solution, and provide the one or more cryptography keys to encrypt or decrypt the data using the cryptography algorithm not supported by the white-box cryptography solution.
