Encryptionizer for SQL Server allows you to achieve column encryption is several ways. The simplest is through the use of our point-and-click user interface called the Column Encryption Manager (Col-E Manager, for short). Your first step is to create the server key. This allows you to choose a strong algorithm, key length (up to 256… Read More
If using the Col-E Manager, when you select the column(s) to be encrypted, the Col-E manager will encrypt the column data on disk, and then create views that control access to the encrypted data. INSTEAD OF triggers are also created to ensure that data is written as encrypted back to the database. You will use… Read More
Column data that is encrypted is backed-up as any other column data would be when SQL databases are backed-up. If you need to restore encrypted data to another machine, that machine must be configured with Encryptionizer with the same key profile settings.
When encrypting data in columns, if a column contains the same value repetitively, that same value will typically be encrypted to the same encrypted value. While someone may not be able to discern what that encrypted value is, they will be able to determine all the records that have that same value. For columns that… Read More
You start by using an included provided User Interface (or available Command-Line-Interface) to encrypt a database with a high level Encryption algorithm, a selected key length (up to 256 bit) and a pass-phrase. Next, you use another utility to secure your instance of SQL Server, MySQL or other application with the Encryptionizer engine. This allows your… Read More
Transparent Database Encryption encrypts an entire database file. This encrypted database cannot be accessed unless the SQL server, My SQL or other application is then secured with the same key. This prevents anyone from being able to steal the database file and view or attach it elsewhere. And it does this simply, with low maintenance… Read More
Databases on backup media are as much at risk, if not even more so, than databases on the server. Of course you use a backup password, but anyone that needs to perform a backup or a restore needs to know the password. In fact, it is probably taped to the backup console! Encryptionizer can automatically… Read More
This is encryption that takes place at the server machine as opposed to the client machine, as in NEP. With server-side encryption, the encryption drivers only need to reside on the server machine where the database process resides. Encryptionizer for SQL Server and for SQL Express is a server-side encryption tool.
Transparent database encryption and column encryption are actually two completely different methods of providing data encryption. Each has its advantages and limitations. For more information, please follow this link: Differences between transparent database and column encryption.
It seems counter-intuitive. Why would performance when working with a wholly encrypted database be better than performance when working with just a few columns? That is because NetLib’s patented Transparent Database Encryption processing actually takes place between the SQL Server and file system layers. Since Transparent Database Encryption works at such a low level, it… Read More
