Upgrading OpenSSL

NetApp Manageability SDK provides core libraries and OpenSSL libraries. If you want to upgrade your OpenSSL version, you can download OpenSSL source code and build the libraries for your applications.

Prerequisites

You must download the latest version of OpenSSL and extract it to a folder. Perform the following steps to download and extract the latest version of OpenSSL:

Download the OpenSSL tarball by entering http://www.openssl.org/source in your web browser.

Find the latest version of OpenSSL and save the .tar.gz file.

Untar the file: gunzip openssl-x.x.x.tar.gz and tar xvf openssl-x.x.x.tar. A subdirectory named openssl - x.x.x is created.

Building OpenSSL libraries in Linux, Solaris, HP-UX, and AIX platforms

To build OpenSSL libraries in Linux, Solaris, HP-UX, and AIX platforms, perform the following steps:

Change directory: $ cd openssl-x.x.x

Configure OpenSSL: $ ./config shared no-krb5 no-rc5 no-idea no-asm -fno-strict-aliasing

Resolve dependencies: make depend

Generate OpenSSL libraries: make

Static libraries libcrypto.a and libssl.a, and dynamic libraries libcrypto.so and libssl.so are created in the openssl-x.x.x directory.

If you are using the dynamic version of OpenSSL libraries, create a soft link to the new OpenSSL dynamic libraries to link them with your application: for example, ln -s libcrypto.so libcrypto.so.x.x.x and ln -s libssl.so libssl.so.x.x.x.

Building OpenSSL libraries in a Windows platform

To build OpenSSL libraries in a Windows 32-bit platform, perform the following steps:

Navigate to the OpenSSL extract folder from the Visual Studio command prompt.

Configure OpenSSL: perl Configure VC-WIN32 no-asm no-idea no-rc5 > win-config.out

The configuration information is saved in the win-config.out file.

Execute: ms\do_ms.bat

ms\ssleay32.def, ms\libeay32.def, ms\ntdll.mak, ms\nt.mak and ms\version32.rc files are generated.

Generate OpenSSL dynamic libraries: nmake -f ms\ntdll.mak

New libraries libeay32.dll and ssleay32.dll are created in the openssl-x.x.x/out32dll directory.

To build OpenSSL libraries in a Windows 64-bit platform, perform the following steps:

Navigate to the OpenSSL extract folder from the Visual Studio x64 cross tools command prompt.

Configure OpenSSL: perl Configure VC-WIN64A no-asm no-idea no-rc5 > win-config.out

The configuration information is saved in the win-config.out file.

Ensure that the path for ml64.exe is added to environment variable path. ml64.exe is located in C:\Program Files (x86)\Microsoft Visual Studio 8\VC\bin\x86_amd64\.

Execute: ms\do_win64a.bat

Generate OpenSSL dynamic libraries: nmake -f ms\ntdll.mak

New libraries libeay32.dll and ssleay32.dll are created in the openssl-x.x.x/out32dll directory.
