This tutorial works with OpenSSL 1.0.0a and Xcode 3.2.3 with iOS 4.

You can find the tutorial for OpenSSL 0.9.8 at http://www.x2on.de/2010/02/01/tutorial-iphone-app-with-compiled-openssl-library/

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

Create OpenSSL Libary:

Download OpenSSL Sourcecode
Change in crypto/ui/ui_openssl.c

static volatile sig_atomic_t intr_signal;

to

static volatile int intr_signal;

for preventing building error

Build OpenSSL for i368 iPhoneSimulator:

mkdir ssllibs
cd openssl-1.0.0a
mkdir openssl_armv6 openssl_armv7 openssl_i386
./configure BSD-generic32 --openssldir=/Users/<username>/openssl-1.0.0a/openssl_i386

Edit Makefile:

Change CC = cc to:

CC= /Developer/Platforms/iPhoneSimulator.platform/Developer/usr/bin/gcc -arch i386

Add as first item to CFLAG:

-isysroot /Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator4.0.sdk

Build it:

make
make install

Your libcrypto.a and libssl.a are in the folder openssl_i368/lib

Build OpenSSL for armv6 iOS:

mv openssl_i386 ../ssllibs
make clean
./configure BSD-generic32 --openssldir=/Users/<username>/openssl-1.0.0a/openssl_armv6

Edit Makefile:

Change CC = cc to:

CC= /Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/gcc -arch armv6

Add as first item to CFLAG:

-isysroot /Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS4.0.sdk

Build it:

make
make install

Your libcrypto.a and libssl.a are in the folder openssl_armv6/lib

Build OpenSSL for armv7 iOS:

mv openssl_armv6 ../ssllibs
make clean
./configure BSD-generic32 --openssldir=/Users/<username>/openssl-1.0.0a/openssl_armv7

Edit Makefile:

Change CC = cc to:

CC= /Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/gcc -arch armv7

Add as first item to CFLAG:

-isysroot /Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS4.0.sdk

Build it:

make
make install

Your libcrypto.a and libssl.a are in the folder openssl_armv7/lib

Create universal libs:

cp -r openssl_armv7/include ../ssllibs/
lipo -create ../ssllibs/openssl_i386/lib/libcrypto.a ../ssllibs/openssl_armv6/lib/libcrypto.a openssl_armv7/lib/libcrypto.a -output ../sslibs/libcrypto.a
llipo -create ../ssllibs/openssl_i386/lib/libssl.a ../ssllibs/openssl_armv6/lib/libssl.a openssl_armv7/lib/libssl.a -output ../sslibs/libssl.a

Edit your iPhone-XCode project:

Copy the “include” folder from OpenSSL into your project-folder
Copy the libcrypto.a and libssl.a files into your project-folder
Drag the libcrypto.a and libssl.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 iOS 3.2/4.0 XCode Project with OpenSSL 1.0.0a libaries. The examples uses the MD5-algorithm to calculate an md5 hash from an UITextfield.

Create OpenSSL Libary:

• Download OpenSSL Sourcecode
• Build OpenSSL for i368 iPhoneSimulator:

  • cd openssl-0.9.8o
    mkdir openssl_arm
    mkdir openssl_i386
    ./config --openssldir=/Users/<username>/openssl-0.9.8o/openssl_i386

  • 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;

    to

    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:

  • mv openssl_i386 openssl_i386_lib
    make clean

  • 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

      to

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

    • Change

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

      to

      -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)
