Interesting info from on the sqlite-users mailing list, about the encryption algorithm used in System.Data.SQLite:At least the original component System.Data.SQLite, available fromuses its own encryption implementation based on a 128-bit RSA cipher (using the Windows Crypto API), while SQLCipher uses a 256-bit AES cipher (using the OpenSSL library). SQLCipher provides a.Net interface (SQLCipher for ADO.NET), which is based on System.Data.SQLite, that is, the SQLCipher guys used the.Net wrapper part of System.Data.SQLite, but replaced the internal implementation of the encryption algorithm by their own implementation.The pageexplains how to use SQLCipherfor ADO.Net together with Visual Studio.Unfortunately the various encryption extensions for SQLite are not compatible, so the developer has to take care that the development environment and the database management tools intended to be used support the same encryption extension.
