Hi its all about building OpenSSL on Windows using Visual C++ (6.0)

Installation folder: C:\www\openssl ( use command mkdir C:\www\openssl)
openssl.cnf location : C:\www\openssl\bin

Build:
1. cd /d C:\build\openssl2
2. perl Configure enable-camellia –openssldir=C:/www/openssl VC-WIN32
3. ms\do_masm
4. nmake -f ms\ntdll.mak

Test the build:
nmake -f ms\ntdll.mak test

Install:
