Thank you for your replys, but I am still not sure I understand how a Query is executed on (page) encrypted data wihout either indexing the data prior to encrption, creating a secondary hash column of the data or simply decrypting every page to get at the underlying data? Would greatly

[sqlite] equality searches and range searches with encrypted data

I am still not clear if page level encryption permits equality searches and range searches? Intuitively it would seem that these searches would require every page to be decrypted to access the column data for each record... unless a proxy Index is used as suggested here
