Abstract
Methods and systems for managing secrets are disclosed. To manage secrets, backups of the secrets may be obtained to facilitate future recoveries of the secrets. While backed up, the secrets may be protected with a security model. The security model may prescribe how decryption keys are maintained, and how various copies of the backed up secrets are to be separated from the decryption keys for encrypted copies of the secrets. When access to a secret is lost, a recovery may be performed using a corresponding encrypted backup of the secret.
