Managing Keys Used for Encrypting Data |
摘要 |
A method, a data processing system, and a computer program product for managing cryptographic information. A determination is made as to whether a first time stamp of when cryptographic information was created is more recent than a second time stamp of a backup of the cryptographic information in response to receiving a request for the cryptographic information from a requester. The cryptographic information is used to encrypt data. The cryptographic information is prevented from being provided to the requester in response to a determination that the first time stamp of cryptographic information creation is more recent than the second time stamp of the backup of the cryptographic information. |
