copied!<p>I found a solution for this.</p> <p>SHA512 is not working (giving incorrect results) with the port of OpenSSL for Android. While working on the Jelly Bean (Android 4.2) AOSP tree (<strong>not</strong> NDK), I noticed that the OpenSSL ($AOSP_ROOT/external/openssl) version is 1.0.1c while the port I was using was 0.9.8.</p> <p>I managed to take OpenSSL 1.0.1c from AOSP and change the *.mk files so that it will compile with NDK, as a static library, although building the shared library is also very simple. This was not very difficult as the NDK build system is a subset of the AOSP build system, but one should have the knowledge of the *.mk file format to do this.</p> <p>I also tried older versions from previous releases (1.0.0, 1.0.1a & b) which also had te same problem with SHA512.</p> <p><strong>In conclusion</strong>: SHA512 on Android will work with any <strong>OpenSSL version higher than 1.0.1c</strong> (including 1.0.1c). Testing 1.0.1c, d & e was successful.</p> <p><a href="https://drive.google.com/file/d/0BxjUX32rdiXyZUU3ME5PR2RheFU/edit?usp=sharing" rel="nofollow">These</a> are my changes, in case anyone needs a (static) build of OpenSSL (1.0.1*<em>c</em>*) with a working SAH512 algorithm, for Android (Architectures: armeabi , armeabi-v7a & x86).</p> <p>To build: Uncompressed, cd into the library's project dir and run 'ndk-build'.</p> <p>BTW - The cause of the bug (I think) was not a missing\incorrect compilation flag, but a bug in the SHA512 ASM code (File: openssl_1.0.1c\crypto\sha\asm\sha512-armv4.S).</p>
