摘要： 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.

摘要： Disclosed herein are systems, methods, and non-transitory computer-readable storage media for wireless data protection utilizing cryptographic key management on a primary device and a backup device. A system encrypts a file with a file key and encrypts the file key twice, resulting in two encrypted file keys. The system encrypts each file key differently and stores a first file key on the primary device and transmits one of the encrypted file keys in addition to the encrypted file to a backup device for storage. On the backup device, the system associates the encrypted file key with a set of backup keys protected by a user password. In one embodiment, the system generates an initialization vector for use in cryptographic operations based on a file key. In another embodiment, the system manages cryptographic keys on a backup device during a user password change.
