From Wikipedia, the free encyclopedia Not to be confused with OpenSSL. OpenSSH (also known as OpenBSD Secure Shell) is a suite of secure networking utilities based on the Secure Shell (SSH) protocol, which provides a secure channel over an unsecured network in a client–server architecture. Feb 06, 2019 OpenSSL is a robust, commercial-grade implementation of SSL tools, and related general purpose library based upon SSLeay, developed by Eric A. Young and Tim J. OpenSSL is available as an Open Source equivalent to commercial implementations of SSL via an Apache-style license. The OpenSSL project does not distribute any code in binary form, and does not officially recommend any specific binary distributions. An informal list of third party products can be found on the wiki. Some third parties provide OpenSSL compatible engines.

OpenSSL is a full-featured toolkit for the Transport Layer Security (TLS) and Secure Sockets Layer (SSL) protocols. It is licensed under an Apache-style license.

Qt 5 / QtWebkit can make use of OpenSSL, which MinGW distributions do not ship.

  • 2Compiling on your own

Pre-built packages

The Win32OpenSSL project provides pre-compiled libraries for both 32 and 64 bit. However, these depend on the Microsoft Visual C++ 2008 runtime being installed.

Inside MSYS2 shell, pre-built openssl can be obtained from MSYS2 repo, with this command: pacman -S openssl

Compiling on your own

Requirements

  • Either use MSYS, or use MSYS2 :
    • MSYS shell command prompt (an sh shell + some UNIX tools, get it from http://sourceforge.net/projects/mingw/files/MSYS/Base/msys-core/msys-1.0.11/MSYS-1.0.11.exe/download?use_mirror=garr. It's also an (optional) part of mingw.org installer). Install it in C:drive in 'msys' folder.
    • MSYS2 shell command prompt, it can be obtained from https://msys2.github.io/ Install it in C:drive in 'msys2' folder.
  • Working MinGW, or MinGW-w64 toolchain:
    • Either get & load MinGW, or, get & load MinGW-w64 toolchains (from their respective project website), or, use 'MinGW-w64' toolchains from MSYS2 repo, inside the MSYS2-shell.
    • NOTE: Do not use (or try to avoid using) different type of toolchains for building different sub-components for the same/main project, when targeted for same platform/OS. If you are using MinGW-w64 based toolchains from MSYS2mingw32 or MSYS2mingw64, then for main project & all sub-components, use same MSYS2 toolchains. If you are using MinGW toolchain, then for all of your sub-components & main project, use same MinGW toolchain. If you are using MinGW-w64 toolchains from 'MinGW-builds', then for all sub-components & main project, use same MinGW-builds toolchains.

How to build

  • Download latest+stable OpenSSL (You must use HTTPS secure encrypted connection to obtain source file) from https://www.openssl.org/source (e.g. openssl-1.0.1c.tar.gz)
  • Either start MSYS-shell, or start MSYS2-shell:
    • Start a MSYS shell command prompt (C:.0msys.bat)
    • Or, start MSYS2 shell command prompt (C:2msys2_shell.bat)
      • See inside this MSYS2 page, how to prepare MSYS2 with build/compile related toolchains, tools & dependencies
  • Extract source tar.gz using MSYS tar or MSYS2 tar (and ignore the symlink warnings)
    • don't use 7zip or other apps, since they fail to set up any symlinks! tar will also complain about symlinks, but compilation will still succeed.
  • Unzip/decompress source:

$ tar xvzf openssl-1.0.1c.tar.gz$ cd openssl-1.0.1c

  • Check that gcc is in PATH, otherwise add it: change below command to match with your-side directory's exact name & letter-case & location:
    • If using MinGW-builds toolchain (which is usually located outside of MSYS or MSYS2), then execute this in MSYS or in MSYS2:

$ export PATH='/c/Mingw-builds/bin:$PATH'

    • If using MSYS shell, and if you have installed MinGW toolchain into C:32 directory, then execute this:

$ export PATH='/c/mingw32/bin:$PATH'

    • If using MSYS2 shell, execute this, if you are building for 32bit:

$ export PATH='/c/msys2/mingw32/bin:$PATH'

  1. or if using 64-bit MSYS2
Wiki

$ export PATH='/c/msys64/mingw32/bin:$PATH'

    • If using MSYS2 shell, execute this, if you are building for 64bit:

$ export PATH='/c/msys32/mingw64/bin:$PATH'

  1. or if using 64-bit MSYS2

$ export PATH='/c/msys64/mingw64/bin:$PATH'

  • Check that you have your PATH correctly setup
  • for MinGW (32 bit) do:

$ ./Configure --prefix=$PWD/dist no-idea no-mdc2 no-rc5 shared mingw

  • for MinGW-w64 do:

$ ./Configure --prefix=$PWD/dist no-idea no-mdc2 no-rc5 shared mingw64

  • Compile & install:

$ make depend && make && make install

check out http://openssl.6102.n7.nabble.com/Compile-error-with-MinGW-w64-td36657.html* Use perl inside MSYS or inside MSYS2* or change crypto/perlasm/x86_64-xlate.pl as mentioned in the e-mail thread.

Using it

  • If you are using cmd.exe (Cmd-shell), then: add the bin, include, lib folders to your compilation environment:

C:> set PATH=PATH;C:–1.0.1cdistbinC:> set INCLUDE=INCLUDE;C:–1.0.1cdistincludeC:> set LIB=LIB;C:–1.0.1cdistlib

  • If you are using MSYS2/MSYS-shell, then: add the bin, include, lib folders to your compilation environment:

$ export PATH='$PATH:/c/openssl-1.0.1c/dist/bin'$ export INCLUDE='$INCLUDE:/c/openssl-1.0.1c/dist/include'$ export LIB='$LIB:/c/openssl-1.0.1c/dist/lib'

Openssl

Openssl For Windows 10 64 Bit

When you now run Qt's configure.exe openssl should be detected, and Qt links against the libraries.
