CATool是 鱼漂[admin.net(#)163.com] 使用DOS命令编写的，一个简单的，生成供Apache使用的数字证书的小工具，CATool运行在Windows操作系统上；此工具已内置openssl，并使用它来生成数字证书。
CATool参考了另外一个Bash写的脚本 ( http://www.openssl.org/contrib/ssl.ca-0.1.tar.gz )，并增加了部分功能。(如果您在Windows中安装Cygwin的话，仍然可以在Windows下使用ssl.ca-0.1.tar.gz，如果没有安装Cygwin，请在Windows下使用CATool).
CATool调用openssl来生成数字证书，生成的证书可以给Windows或Unix(Linux)下的Apache使用，以支持Apahce的HTTPS。
您可以在 http://www.eit.name/catool/ 找到CATool的最新版本和用法。
[[请点击此处下载]] 下载并解压后，打开Windows的DOS命令窗口，进入到CATool目录，您就可以使用里面的几个命令。
请按实际需要，选择以下三种用法之一：
在DOS命令行窗口，进入到CATool目录，分别运行以下命令：
a. CreateRootCA.bat
E:\CATool>CreateRootCA.bat
No Root CA key found, Generating one
Loading 'screen' into random state - done
Generating RSA private key, 1024 bit long modulus
..........................................++++++
...............++++++
e is 65537 (0x10001)
Enter pass phrase for cert\ca.key: <=输入root ca的密码，需要记住此密码
Verifying - Enter pass phrase for cert\ca.key: <=重复输入上面的密码
Self-sign the root CA...
Enter pass phrase for cert\ca.key: <=输入上面的密码，用来签署根证书
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) [CN]: <=以下的内容，按您的实际情况填写
State or Province Name (full name) [GuangDong]:
Locality Name (eg, city) [GuangZhou]:
Organization Name (eg, company) [EIT.NAME]:
Organizational Unit Name (eg, section) [SystemAdmin Team]:
Common Name (eg, MD Root CA) []:EIT CA
Email Address []:admin@eit.name
E:\CATool>
运行上面的命令后，将在Cert/目录，生成ca.key, ca.crt
b. CreateServerCert.bat
E:\CATool>CreateServerCert.bat
Please input the server name:server <=输入Apache的server name(这里的输入决定生成的文件名)
No cert\www.eit.name.key found, Generating one
Loading 'screen' into random state - done
Generating RSA private key, 1024 bit long modulus

将在cert/目录，生成server.crt, server.key两个文件，将这两个文件复制到Apache的conf/目录，并如下配置httpd-ssl.conf
SSLCertificateFile "C:/Apache2/conf/server.crt"
SSLCertificateKeyFile "C:/Apache2/conf/server.key"
在DOS命令行窗口，进入到CATool目录，运行以下命令：
a. SelfSignCert.bat
E:\CATool>SelfSignCert.bat

将在cert/目录下生成的server.csr, server.key文件，将server.csr提交给第三方机构签署，签署后得到server.crt，将server.crt, server.key文件复制到Apache的conf目录。并按如下方式配置：
SSLCertificateFile "C:/Apache2/conf/server.crt"
SSLCertificateKeyFile "C:/Apache2/conf/server.key"
让Apache支持HTTPS，除了需要上面生成的证书和配置外，还需要Apache支持并配置了mod_ssl，详细配置请参考：
http://httpd.apache.org/docs/2.2/ssl/
200804：首次发布，支持自签发CA以及服务器证书的签发；
201404：第二次更新，更新openssl的版本（Win7下运行正常），避免对vc7运行库的依赖，增加客户端证书签发功能．
