DBDefence 2.10 Reference

Database decryption

Database decryption completely removes protection and encryption from the database. It can be applied to detached database. We have implemented it in this way in order to make emergency decryption possible. For example, if DBDefence is not running on the system but you need to work with the database immediately.

To decrypt the database you must provide at least one key file and correct password. Decryption is not possible without those components.

The main window is quite simple. After decryption, the program renames the key file for each decrypted file. For example db.mdf.dbd_key becomes db1.mdf.dbd_key.renamed_by_decrypter.

Important: The decryption process is not interruptible and can be a time consuming operation. If you terminate the process it is likely that your files will be corrupted.  We recommend that you backup any encrypted databases before you attempt the decryption process.
