In a typical implementation of record-level encryption, how many keys does Gary use for his database?

In a typical implementation of record-level encryption, using one key per record provides a distinct advantage in terms of security and access control. By assigning a unique encryption key to each individual record, it ensures that even if one record is compromised, the others remain secure. This method allows for granular control over data access, enabling specific records to be decrypted only by authorized users who possess the correct key.

The use of individual keys means that data can be better protected from various threats, as the exposure of one key does not affect the security of other records. This approach is particularly useful in environments where sensitive information is stored, allowing for better compliance with data protection regulations and policies.

In contrast, employing a single key for the entire database could create a significant risk, as the exposure of that one key would jeopardize the security of all stored records. Therefore, using one key per record is a common practice in scenarios where enhanced security and privacy are required.
