SQLCipherSpeed

A project for testing the speed of SQLCipher on an iOS device, and measuring the impact of the encryption used compared to SQLite.

This fork of the project is a bit of a build-out for the main fork, it stores and displays previous test runs and provides a display averaging those results together.

iOS 4 Only

Please Note: This fork of SQLCipherSpeed requires iOS 4 because it makes use of blocks and Grand Central Dispatch to run the tests without blocking the main run loop. It is not currently compatible with iOS 3 (but if you want to try patching that in, feel free to fork, hack it out, and send us a pull request.)

Prerequisites for Building

Before you build this project, you'll need to load up the submodules used, e.g.:

$ git clone git://github.com/billymeltdown/SQLCipherSpeed.git
$ cd SQLCipherSpeed
$ git submodule init
$ git submodule update

You'll also need to create a source tree in your XCode Preferences named OPENSSL_SRC that points to a checkout of the latest OpenSSL source on your workstation. Check http://openssl.org/source/ for the latest version, below is just an example.

$ curl -C - -O http://openssl.org/source/openssl-1.0.0e.tar.gz
$ tar xf openssl-1.0.0e.tar.gz
$ cd openssl-1.0.0e
$ pwd

Setting up the source tree:

1. Copy the output of the pwd command above to your clipboard, make sure you get the whole path
2. In Xcode, navigate to Preferences -> Source Trees
3. Use the + button to create a new one, name it OPENSSL_SRC, and paste the path to OpenSSL from your clipboard

Cipher Page Size

There's a textfield on the main screen for running the tests, labeled "Page Size." Currently it doesn't do anything on the latest stable version of SQLCipher, but it does get used by the next version currently in development, SQLCipher branch v2beta, which allows the user to do something like PRAGMA cipher_page_size=1024 to set a custom page size.
