利用keytool/Openssl来生成服务端和客户端证书，根证书。

1.首先下载openssl并安装，然后将D:\\zhengshu\\OpenSSL-Win32\\bin这个路径放到环境变量path里面（要根据具体openssl安装的位置）

2.安装jdk（最好是1.7以上，我用的是1.7）

然后在cmd下面开始执行以下命令：

C:\\Users\\Administrator>d:

D:\\>mkdir server

D:\\>mkdir client

D:\\>mkdir demoCA

并在demoCA中新建空文本文件 index.txt、index.txt.attr、serial

D:\\>mkdir demoCA\\certs

D:\\>mkdir demoCA\\newcerts

一、产生ca根证书

D:\\>openssl genrsa -out demoCA\\ca-key.pem 1024

D:\\>openssl req -new -out demoCA\\ca-req.csr -key demoCA\\ca-key.pem

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) \[Some-State\]:gd

Locality Name (eg, city) \[\]:gz

Organization Name (eg, company) \[Internet Widgits Pty Ltd\]:sinobest

Organizational Unit Name (eg, section) \[\]:sinobest

Common Name (e.g. server FQDN or YOUR name) \[\]:songbo

Email Address \[\]:

Please enter the following 'extra' attributes

to be sent with your certificate request

A challenge password \[\]:123456

An optional company name \[\]:

D:\\>openssl x509 -req -in demoCA\\ca-req.csr -out demoCA\\ca-cert.pem -signkey demoCA\\ca-key.pem -days 365

Signature ok

subject=C = cn, ST = gd, L = gz, O = sinobest, OU = sinobest, CN = songbo

Getting Private key

二、生成服务端证书

D:\\>keytool -genkey -alias tomcat\_server -validity 365 -keyalg RSA -keysize 1024 -keypass 123456 -storepass 123456 -keystore server\\server\_keystore

您的名字与姓氏是什么?

\[Unknown\]: songbo  //这个要填写自己本机的IP

您的组织单位名称是什么?

\[Unknown\]: sinobest

您的组织名称是什么?

\[Unknown\]: sinobest

您所在的城市或区域名称是什么?

\[Unknown\]: gz

您所在的省/市/自治区名称是什么?

\[Unknown\]: gd

该单位的双字母国家/地区代码是什么?

\[Unknown\]: cn

CN=songbo, OU=sinobest, O=sinobest, L=gz, ST=gd, C=cn是否正确?

\[否\]: y

D:\\>keytool -certreq -alias tomcat\_server -sigalg MD5withRSA -file server\\server.csr -keypass 123456 -keystore server\\server\_keystore -storepass 123456

D:\\>openssl x509 -req -in server\\server.csr -out server\\server-cert.pem -CA demoCA\\ca-cert.pem -CAkey demoCA\\ca-key.pem -CAserial demoCA/ca-cert.srl -CAcreateserial -days 365

Signature ok

subject=C = cn, ST = gd, L = gz, O = sinobest, OU = sinobest, CN = songbo

Getting CA Private Key

D:\\>keytool -importcert -v -trustcacerts -alias my\_ca\_root -file demoCA\\ca-cert.pem -keystore server\\server\_keystore

输入密钥库口令:

再次输入新口令:

所有者: CN=songbo, OU=sinobest, O=sinobest, L=gz, ST=gd, C=cn

发布者: CN=songbo, OU=sinobest, O=sinobest, L=gz, ST=gd, C=cn

三、生成客户端

D:\\>openssl genrsa -out client\\client-key.pem 1024

D:\\>openssl req -new -out client\\client-req.csr -key client\\client-key.pem

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.

注：导出根证书 安装到IE受信任根证书中

D:\\>openssl x509 -inform PEM -in demoCA\\ca-cert.pem -out demoCA\\ca.crt

注：给客户端签名

D:\\>openssl ca -in client\\client-req.csr -out client/client.crt -cert demoCA\\ca.crt -keyfile demoCA\\ca-key.pem -notext -config D:\\zhengshu\\OpenSSL-Win32\\bin\\cnf\\openssl.cnf   //这个地址填写自己SSL目录地址
