Tutorial: iPhone App with compiled OpenSSL Library

01. Februar 2010

This is a tutorial for using self-compiled builds of the OpenSSL-library on the iPhone. You can build apps with XCode and the official SDK from Apple with this. I also made a small example-app for using the libraries with XCode and the iPhone/iPhone-Simulator. You can also download the precompiled OpenSSL-library (0.9.8m-beta1).

You can get the Source of the example app with compiled OpenSSL athttp://github.com/x2on/OpenSSL-for-iPhone

Create OpenSSL Libary:

Download OpenSSL Sourcecode

Build OpenSSL for i368 iPhoneSimulator:

cd openssl-0.9.8m
mkdir openssl_arm
mkdir openssl_i386
./config --openssldir=/Users/

Edit Makefile:

Change CC = cc to:

CC= /Developer/Platforms/iPhoneSimulator.platform/Developer/usr/bin/gcc-4.0

Add as first item to CFLAG:

-isysroot /Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator3.1.2.sdk

Change in crypto/ui/ui_openssl.c

static volatile sig_atomic_t intr_signal;

static volatile int intr_signal;

for preventing building error

Build it:
```
make
make install
```
Your libcrypto.a and libssl.a are in the folder openssl_i368/lib
Rename the two files to libcrypto_i386.a and libssl_i386.a

Build OpenSSL for arm iPhoneOS:

Edit Makefile:

Search and replace openssl_i386 with openssl_arm
Change -arch i386 in CFLAG to:
-arch armv6

Change

CC=  /Developer/Platforms/iPhoneSimulator.platform/Developer/usr/bin/gcc-4.0

CC=  /Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/gcc-4.0

Change

-isysroot  /Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator3.1.2.sdk

-isysroot  /Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS3.1.2.sdk

Build it:
```
make
make install
```
Your libcrypto.a and libssl.a are in the folder openssl_arm/lib
Rename the two files to libcrypto_arm.a and libssl_arm.a

Edit your iPhone-XCode project:

Copy the “include” folder from OpenSSL into your project-folder
Copy the libcrypto_*.a and libss_*.a files into your project-folder
Drag the libcrypto_*.a and libss_*.a files into your XCode Framework Folder-Tree
Open the Build-Info from your “Target” (Righclick on Target – Get Info)
Change Library Search Paths to
```
$(inherited) "$(SRCROOT)"
```
Change User Header Search Paths to include
Activate Always Search User Paths

Enjoy OpenSSL on the iPhone!

I have made an iPhone OS 3.1.2 XCode Project with OpenSSL 0.9.8m (Beta1) Libaries. The examples uses the MD5-algorithm to calculate an md5 hash from an UITextfield.
