How to build
参考 OpenSSL文件中
- INSTALL.md
- NOTES-WINDOWS.md
- NOTES-UNIX.md
- NOTES-ANDROID.md
1. 下载
- strawberry-perl-5.32.1.1-64bit.msi
- nasm
2. set env 设置环境变量
- perl (MSI auto set env)
- nasm (should set env by self)
- openSSL
3. build
a.打开x64命令行工具
b.运行configure
perl Configure VC-WIN64A （Release版本）
perl Configure debug-VC-WIN64A （Debug版本）
perl Configure VC-WIN32 （Release版本）
perl Configure debug-VC-WIN32 （Debug版本）
// 指定openSSL目录，指定生成位置 lib（*.lib）,bin(dll),include(header),html(?)
perl Configure VC-WIN64A --prefix=G:\Temp\ssl\openssl-openssl-3.0.2\Output
nmake
nmake test
nmake install
以下结果正确
*** Installing runtime programs
Copying: apps//openssl.exe to G:/Temp/ssl/openssl-openssl-3.0.2/Output/bin/openssl.exe
Copying: apps//openssl.pdb to G:/Temp/ssl/openssl-openssl-3.0.2/Output/bin/openssl.pdb
Copying: tools//c_rehash.pl to G:/Temp/ssl/openssl-openssl-3.0.2/Output/bin/c_rehash.pl
Cannot create directory C:/Program Files/Common Files/SSL: Permission denied
NMAKE : fatal error U1077: 'C:\Strawberry\perl\bin\perl.exe' : return code '0x2'
Stop.
因为访问权限，所以install 无法安装到 C:/Program Files/Common Files/SSL 中

版本区别1.x与 3.x
================
openssl 1.x.x 生成 libeay32.dll, ssleay.dll
openssl 3.x.x 生成 libssl.dll，libcrypto.dll
So while previously in 1.0.x there were libeay32 and ssleay32,
they are in 1.1.x named libssl and libcrypto
(在1.0.x之前的版本中,文件为libeay32.dll和ssleay32.dll,在1.1.x之后的版本中，名字是libssl.dll和libcrypto.dll)
改变说明 http://www.npcglib.org/~stathis/blog/precompiled-openssl/
The complete explanation is that 1.0.x and 1.1.x do not have the same naming conventions for the generated libraries. OpenSSL 1.1.x has moved into what they call the “unified build system” and changed themselves the names of the libraries. This was done on purpose, mainly because these libraries are not binary compatible and should not be intermixed into projects or dlls deployed to replace 1.0.x with 1.1.x, and vice versa. So while previously in 1.0.x there were libeay32 and ssleay32, they are in 1.1.x named libssl and libcrypto(在1.0.x之前的版本中,文件为libeay32.dll和ssleay32.dll,在1.1.x之后的版本中，名字是libssl.dll和libcrypto.dll). That’s what happened upstream in OpenSSL. Read here also: https://marc.info/?l=openssl-dev&m=147223063610803&w=2 and there are tons of other discussions online you can tap to.
Beyond that, I also manipulate the suffixes in my builds. Namely, I append the MD[d] and MT[d] suffixes, so that it can be clearer when someone uses a library. This may not be very important when using DLLs, but with static builds chaos ensues if you mix them. So I made my own patches to produce these suffixes to the libraries.
I think that’s a complete answer now. I have also a suggestion for you:
You can download my build scripts if you still like to change the names of the library files in a different way and look at the patch, and modify it accordingly.
You can also skip the application of the patch and then you will get exactly the filenaming conventions of OpenSSL upstream in different builds.
I hope this helps.
使用DLL
VS工程导入DLL（或静态库）确认好编译的版本,x86,x64
1. [c/c++]->[Additional Library Directories] add include header
2. [link] -> [input] 设置lib目录，
3. [link] -> [Additional Library Directories] 添加 libcrypto.lib libssl.lib
代码使用
参考
- ./demos 目录 cipher/aesgcm.c signature\EVP_Signature_demo.c 等等
- ./test 目录 aesgcmtest.c 等等
- ./apps/openssl.exe 相关源码(因为涉及cmd，调用各种加密算法)
Tips：
网上很多示例代码，调用后，都会说deprecated since openSSL 3.0 ， 接口API需要更换，
某些doc 可能未完成，参考上文中的 wiki https://wiki.openssl.org/index.php/OpenSSL_3.0
