Encrypted Sqlite connection

[jota]

Hi

I have an encrypted Sqlite database with SQLCipher.

I've been looking tuniconnection object and i don´t know where and how express 'PRAGMA key = "password"' and any other information that may be necessary to access this encrypted database.

Can anyone help me with the required code and syntax?

Thanks in advance.

Hello,

UniDAC supports two modes: Direct and using SQLite library. In the first mode, the encryption algorithms implemented by us (RC4, Cast128, AES256, AES192, AES128, Blowfish, TripleDES) are used, in the second mode - the algorithm embedded in the SQLite library. Since the algorithms implementation is different, a DB encrypted by different programs and libraries cannot be opened. Therefore you should encrypt your DB with UniDAC, but not SQLCipher.
There is a code below for opening an encrypted DB (there is no need to invoke PRAGMA for key installation)

Code: Select all

  UniConnection1.ProviderName := 'SQLite';
  UniConnection1.Database := 'encrypt.db3';
  //for Direct Mode
  UniConnection1.SpecificOptions.Values['Direct'] := 'True';
  UniConnection1.SpecificOptions.Values['EncryptionAlgorithm'] := 'leAES256';
  //----------------------------------
  UniConnection1.SpecificOptions.Values['EncryptionKey'] := '12345'
  UniConnection1.Connect;
