    • Example embodiments provide various techniques for storing and recovering a cryptographic key identifier that may be used to recover encrypted data. The cryptographic key identifier may be stored with the encrypted data itself. In an example, the cryptographic key identifier may be stored in particular blocks on a logical disk that are specifically designated to store the cryptographic key identifier. To store the cryptographic key identifiers in the designated blocks, the data within the blocks is compressed to fit the cryptographic key identifiers within the blocks. This cryptographic key identifier can be recovered at a later time by locating the designated blocks and retrieving the cryptographic key identifier from the blocks.
    • 示例性实施例提供了用于存储和恢复可用于恢复加密数据的加密密钥标识符的各种技术。 加密密钥标识符可以与加密数据本身一起存储。 在一个示例中,密码密钥标识符可以被存储在专门指定用于存储加密密钥标识符的逻辑盘上的特定块中。 为了将加密密钥标识符存储在指定的块中,块内的数据被压缩以适应块内的加密密钥标识符。 可以在稍后时间通过定位指定块并从块中检索加密密钥标识符来恢复该加密密钥标识符。
