+#### Build 32-bit openssl, zlib and openssh following 32-bit instructions.  OpenSSH tools are always 32-bit.
+
+#### STEP 1:  Prepare the Cygwin 64 bit environment
+
+##### 1. Download the Cygwin 64 bit installer from  www.cygwin.com
+
+##### 2. Launch the Cygwin installer, and ensure that packages listed below are selected as  'install':
+
+   devel/mingw-*
+
+   devel/mingw64-*
+
+   perl/*
+
+   devel/make: GNU Tool
+
+   devel/autoconf
+
+   devel/autoconf-2.69-2
+   
+   See REFERENCE VERSIONS below for the detailed list of packages used for reference build.
+
+#### STEP 2: Compile
+
+##### 1. Ensure that you are using correct mingw64 toolchain. You must have administrative rights.
+   
+   To do that you must create symbolic links:
+
+   run [openssh_dir]/scripts/set-mingw64.sh from the Cygwin /bin directory.
+
+##### 2. Prepare the 64-bit libssl.a and libcrypto.a libraries and the openssl headers. These libraries are used by 64-bit ssh-lsa.
+
+   - Move clean OpenSSL sources into another directory, e.g. openssl-64.
+
+   - Compile sources by running:
+
+     $./Configure mingw64
+
+     $make
+
+##### 3. Build 64-bit ssh-lsa for native RSA/DSA key authorization
+
+  - Move to [openssh_directory]/contrib/win32/win32compat/lsa directory and run:
+
+    $export LIBSSL_PATH="OPENSSL_DIR"
+
+    $make -f Makefile.mingw64
+
+     where OPENSSL_DIR is a directory where openssl sources are extracted
+    
+  - This command should produce 64-bit ssh-lsa.dll file.
+
+#### STEP 3 - Install ssh-lsa on system where sshd server is running
+
+- Copy the ssh-lsa.dll to the %WINDIR%/System32 directory.
+ 
+IMPORTANT NOTE:
+
+If your Windows is at 64-bit, be sure that you use a 64-bit file manager to copy ssh-lsa.dll, otherwise this dll will be not visible on the 64-bit OS.
+
+For example:
+
+- Drag and drop file using Windows explorer.
+
+Or:
+
+-  Run copy ssh-lsa.dll c:/windows/system32 under a cmd.exe console. 
+
+- Then, by using the regedit tool, add 'ssh-lsa' string to the end of the registry key below:
+
+    HKEY_LOCAL_MACHINE/SYSTEM/CurrentControlSet/Control/Lsa/Authentication Packages
+ 
+
+Reboot the machine.
