Column level encryption

Column-level encryption is a database security feature that allows data encryption at the individual column level rather than encrypting entire tables or databases. This means that specific columns in a database table can be encrypted to protect sensitive information, while other columns can remain unencrypted and accessible. ### Key Features of Column-Level Encryption: 1. **Granularity**: Only targeted columns containing sensitive information (like personal identification numbers, credit card information, or health records) are encrypted, allowing more efficient use of resources.
