System.Data.SQLite

 Hi

 I'm developing a biometric Credential Provider's for Windows, and I'm storing fingerprint information to database. This information should be encrypted on a database for increase the system security.
Now I'm studying the possibility of include System.Data.Sqlite dll, but when call sqlite_key(...) function in logon context, I get returns 2. Otherwise, when I execute this code in a normal context works properly.

Sample code:
//Logon context

int error = sqlite3_open("C:\\WINDOWS\\system32\\testpw2.db3", &db);
error = sqlite3_key(db,"1111",strlen("1111")); //error = 2 ->SQLITE_INTERNAL(An internal logic error in SQLite)

//Normal context:

int error = sqlite3_open("C:\\WINDOWS\\system32\\testpw2.db3", &db);
error = sqlite3_key(db,"1111",strlen("1111")); //SQLITE_OK

Can help me anyone?

PD:Sorry for my poor English.

Thanks and regards,

Hi Héctor. Your question is general to SQLite, rather than specific to the managed wrapper System.Data.SQLite. Therefore, you probably can get a better and faster response from the 'sqlite-users' mailing list: http://www.sqlite.org/support.html
