Abstract
Disclosed herein are systems, methods, and non-transitory computer-readable storage media for encryption and key management. The method includes encrypting each file on a computing device with a unique file encryption key, encrypting each unique file encryption key with a corresponding class encryption key, and encrypting each class encryption key with an additional encryption key. Further disclosed are systems, methods, and non-transitory computer-readable storage media for encrypting a credential key chain. The method includes encrypting each credential on a computing device with a unique credential encryption key, encrypting each unique credential encryption key with a corresponding credential class encryption key, and encrypting each class encryption key with an additional encryption key. Also disclosed is a method of verifying a password by decrypting a key bag, retrieving data from an encrypted file using an encryption key from the decrypted key bag, and verifying the password by comparing retrieved data with expected data.
