使用Openssl一键生成pem和der证书

1. 将以下代码另存为后缀名为sh的文件

#!/bin/bashPASS=Init_Selection() {    clear    echo "+------------------------------------------------------------------------+"    echo "|                       _ _  _  _        _  _  _  _                    |"    echo "|                      / / //_|/_//_//_//_//_'/ //_/                   |"    echo "|                                 _/   /         _/                    |"    echo "+------------------------------------------------------------------------+"    echo "|                            openssl证书生成脚本v1.0                      |"    echo "+------------------------------------------------------------------------+"    echo "|                         https://www.maoyupeng.club                     |"    echo "+------------------------------------------------------------------------+"        Echo_Green "请输入证书密码"    read -p "Password:" PASS    action_build     }action_build() {    echo "创建AES256加密密钥..."    openssl genrsa -passout pass:${PASS} -out rsa_aes_private.pem 2048    echo "生成公钥..."    openssl rsa -in rsa_aes_private.pem -passin pass:${PASS} -pubout -out rsa_public.pem    echo "PEM私钥转DER..."    openssl rsa -in rsa_aes_private.pem -passin pass:${PASS} -out rsa_private_key.der -outform der    echo "PEM公钥转DER..."    openssl rsa -in rsa_public.pem -out rsa_public_key.der -pubin -outform der    echo "Finish!"}Echo_Green(){  echo $(Color_Text "$1" "32")}Echo_Yellow(){  echo $(Color_Text "$1" "33")}Init_Selection

1. 然后打开终端, 赋予权限

chmod -R 755 ./*.sh

1. 最后执行脚本文件, 根据提示输入生成证书的密码

./xxx.sh

1. 等待片刻, 证书生成成功
