Hi Erel,
Unfortunately the client requires the entire database file to be encrypted, I had to send them two database files one encrypted and one unencrypted, they only signed the deal off on the encrypted one... that was why SQLCipher is ideal.
The company are willing to purchase the licences required, we will be looking at supplying the software we created on iOS some time in the new year so I am looking into what's involved.
Regards
Steve
