Openssl生成CSR文件方法

一 下载OPENSSL，并解压缩到D:\OpenSSL目录下。

二 进入cmd执行下面命令

C:\Users\cakin>cd D:\OpenSSL\bin C:\Users\cakin>d: D:\OpenSSL\bin>openssl req -new -nodes -newkey rsa:2048 -keyout domain.key -out domain.csr Loading 'screen' into random state - done Generating a 2048 bit RSA private key ......................+++ ....................+++ writing new private key to 'domain.key' ----- You are about to be asked to enter information that will be incorporated into your certificate request. What you are about to enter is what is called a Distinguished Name or a DN. There are quite a few fields but you can leave some blank For some fields there will be a default value, If you enter '.', the field will be left blank. ----- Country Name (2 letter code) [AU]:cn State or Province Name (full name) [Some-State]:sanxi Locality Name (eg, city) []:xian Organization Name (eg, company) [Internet Widgits Pty Ltd]:network technology Organizational Unit Name (eg, section) []:IT Common Name (eg, YOUR name) []: Email Address []: Please enter the following 'extra' attributes to be sent with your certificate request A challenge password []: An optional company name []:
