This script builds OpenSSL 1.0.1b for iOS.

It builds multi-architecture libaries with armv6, armv7 and i386.

This script is known to work with the following combination of software versions:

 * MacOS X 10.7.3
 * XCode 4.3.2 & iOS SDK 5.1

The compiled libraries should be downward compatible to iOS 4.0 at least.

Building is done by invoking the script:


It will take about 5 minutes on a modern Mac. The result of the build can be found at:

 lib/ - will contain libssl.a and libcrypto.a
 include/ - will contain all OpenSSL headers

If you just want cryptographic functions then you can skip libssl.a and just add
libcrypto.a to your project.

Making your code find the OpenSSL headers works best if the path to the include director is
added to the 'Header Search Paths' in your target settings.

The Example directory contains a little sample app. It calculates a SHA1 digest using
the OpenSSL API.


I included pre-compiled binaries of the openssl libraries in this project mostly for my
own convenience. But you should really not trust me and do two things:

 1) Verify that the openssl-1.0.1b.tar.gz file is authentic by comparing it's SHA1
    hash to the one found on You can do this with
    the 'openssl sha1 openssl-1.0.1b.tar.gz' command.
 2) Compile your own version of the library as explained above

Enjoy :-)
