This is so strange, key/rekey before starting the backup didn't work for me,
what work is to call sqlite3_rekey after sqlite3_backup_finish, but what I
don't like is that the backup database is not encrypted until the backup
finishes.
Can SQLite team comment on this?
Thanks
Ulric
int backupDb(sqlite3 *pDb, const char *zFilename, const char *zKey)
{
int rc;
sqlite3 *pBackupDb;
sqlite3_backup *pBackup;
rc = sqlite3_open(zFilename, &pBackupDb);
if( rc==SQLITE_OK )
{
pBackup = sqlite3_backup_init(pBackupDb, "main", pDb, "main");
if( pBackup )
{
do
{
rc = sqlite3_backup_step(pBackup, 100);
if( rc==SQLITE_OK || rc==SQLITE_BUSY || rc==SQLITE_LOCKED ){
sqlite3_sleep(10);
}
}
while( rc==SQLITE_OK || rc==SQLITE_BUSY || rc==SQLITE_LOCKED );
sqlite3_backup_finish(pBackup);
}
rc = sqlite3_errcode(pBackupDb);
if (zKey != NULL)
sqlite3_rekey(pBackupDb, zKey, strlen(zKey));
}
sqlite3_close(pBackupDb);
return rc;
}

Hi,
sorry.. my fault. It should be:
if (zKey != NULL)
{
sqlite3_key(pBackupDb, NULL, 0);
sqlite3_rekey(pBackupDb, zKey, strlen(zKey));
}
Thats works for me..
