VFS is one way you can't reasonably do it. The VFS is handed full size pages, so the checksums would have to be stored somewhere other than the page. That leads to a *very* complex implementation. The encryption extension does something like defining SQLITE_HAS_CODEC and then gets to use a small amount of each page to store information about the encryption of that page. Checksums would fit very well into a similar implementation. Roger
