Abstract: Exemplary methods, apparatuses, and systems generate an encryption key based upon data content of a portion of data to be encrypted by the encryption key. The encryption key is stored as one of a plurality of encryption keys within a subset of storage. Each of the plurality of encryption keys is generated based upon corresponding data content. A checksum representing the plurality of encryption keys is calculated. In response to receiving an input/output (I/O) request for data encrypted by the encryption key, a verification checksum representing the plurality of encryption keys is calculated. The requested data is decrypted using the encryption key in response to verifying the checksum and verification checksum match.
