本文使用OpenSSL工具生成国密算法SM2的三级CA证书,组成证书链,并使用证书链签名客户端证书和服务端证书。 可以通过证书链对生成的客户端和服务端证书进行校验。 虽然OpenSSL工具可以使用SM2算法来生成并校验证书…
openssl生成SM2的公钥和私钥 OpenSSL源码编译 1.1. 环境 WIN7 64bit, vs2013。 1.2. 编译 1)下载OpenSSL源码,解压至C盘根目录; 2)安装ActivePerl; 3)cmd.exe,进入openssl源码目录,执行命令“perl Configure VC-WIN32”; 4)执行命令“ms\do_ms”; 5)切换至目录“C:\Program Files\Microsoft Visual Studio 12....
As for #8435, my viewpoint is that we should be unable to generate a signature with such invalid key, namely, you will always get a nullptr when sm2_do_sign with d == (N -1). And the issue here is quite different. It can reach the result and return a (r,s). Exactly, I don...

两种方法交叉编译openssl静态库:方法1:a.先配置好交叉编译环境先配置好交叉编译环境(对于配置我主机中的L170交叉编译环境),即: b.配置Makefile 说明: no-asm:在交叉编译过程中不使用汇编代码代码加速编译过程.原因是它的汇编代码是对arm格式不支持的 no-shared:
