I believe I have successfully compiled the lib for OpenSSL Fips module for iOS. But when I try to run the demo app provided by OpenSSL (fips-pi). I ran into the exception

EXC-ARM-DA-ALIGN

with method 

FIPS_mode_set(1 /*on*/);

I understand that the problem is caused by memory alignment. But since I do not have any access to the source code of the Fips module lib, I cannot debug out the cause of the exception.

Is there any other solution to get away with this error?

Edit:

I followed the official user guid User Guide for the OpenSSL FIPS Object Module v2.0

Hardware: iPhone4s (OpenSSL Fips Module is only valid for armv7 device)

iOS version: 8.1.2

Xcode:V6.3.2

XcodeSDK: iOS8.3

  • What hardware, what version of iOS, what version of Xcode/SDK, and finally, where did you get your instructions for building the FIPS Object Module (the validated crypto) and the FIPS Capable Library (capable of using the validated crypto in a plug-in like architecture)? – jww Jul 24 '15 at 00:53
  • @jww Thank you for the reply. I have updated the question to provide more info about the environment. – Summer Jul 24 '15 at 13:25
