openssl3.2/test/certs - 044 - 8192-bit leaf key

openssl3.2/test/certs - 044 - 8192-bit leaf key

概述

openssl3.2 - 官方demo学习 - test - certs

笔记

/*!
* \file D:\my_dev\my_local_git_prj\study\openSSL\test_certs\044\my_openssl_linux_doc044.txt
* \note openssl3.2/test/certs - 044 - 8192-bit leaf key
* 在\test\certs\setup.h中, 最长的密钥就是8192位了.
* 明显的感觉到生成密钥时, 用时长了, 大概3秒钟
* 生成证书请求和证书不费时间
