Encrypting data

You can choose to either encrypt or obfuscate an UltraLite database using the UltraLite C++ API. Encryption provides very secure representation of the data in the database whereas obfuscation provides a simplistic level of security that is intended to prevent casual observation of the contents of the database.

For background information, see Choosing database creation parameters for UltraLite.

Encryption

To create a database with encryption, specify an encryption key by specifying the key= connection parameter in the connection string. When you call the CreateDatabase method, the database is created and encrypted with the specified key. See UltraLite DBKEY connection parameter.

Use the ChangeEncryptionKey method to change the encryption key for an existing database. See ChangeEncryptionKey method.

After the database is encrypted, all connections to the database must specify the correct encryption key. Otherwise, the connection fails.
