写在前面
准备环境
创建CA
创建证书并安装到apache
创建证书并安装到tomcat
创建证书和导入到Thunderbird
创建证书并签名.net文件
创建证书并签名jar文件

 

OS和Openssl

简单的说，一个LINUX的环境即可。因为openssl一般是标配。比如，我的CentOS里，通过

yum -y install openssl openssl-devel

即可安装好openssl套件。

目录

我这里，把工作目录设置在/etc/openssl/。

mkdir –p /etc/openssl/

签名脚本

另外，为了简化工作，我还用用到了一个脚本sign.sh。我把它放在/sbin/里的。它的内容是

#!/bin/sh
##
##  sign.sh -- Sign a SSL Certificate Request (CSR)
##  Copyright (c) 1998-1999 Ralf S. Engelschall, All Rights Reserved.
##

#   argument line handling
CSR=$1
if [ $# -ne 1 ]; then
echo "Usage: sign. .csr"; exit 1
fi
if [ ! -f $CSR ]; then
echo "CSR not found: $CSR"; exit 1
fi
case $CSR in
*.csr ) CERT="`echo $CSR | sed -e 's/\.csr/.crt/'`" ;;
* ) CERT="$CSR.crt" ;;
esac

#   make sure environment exists
if [ ! -d /etc/openssl/ca.db.certs ]; then
mkdir /etc/openssl/ca.db.certs
fi
if [ ! -f /etc/openssl/ca.db.serial ]; then
echo '01' >/etc/openssl/ca.db.serial
fi
if [ ! -f ca.db.index ]; then
cp /dev/null /etc/openssl/ca.db.index
