Openssl CA证书生成以及双向认证

首先本文主要参照这篇文章写的
http://h2appy.blog.51cto.com/609721/1181234

只是途中有些问题折腾了一下,比如openssl.cnf如何来的,这个文件在编译完openssl后,应该openssl根目录下/apps/demoCA有个,可以把他拷贝到openssl.exe同一级目录
里面有些目录配置,自己可以修改下,但是我没有修改,所以最后生成的文件路径必须按openssl.cnf里面来,至于如何编译openssl 请参考我的另一篇文章

开始生成证书,需要提前做一些准备,生成一些特定目录,这些目录和openssl.cnf里面配置要求一致,在demoCA目录下,还需要建立一个index.txt,index.txt.attr空文件,以及serial文件,serial文件里面写00
注意每次输入下一步命令前,如果index.txt serial文件内容发生改变,请把index.txt中的内容清空,serial重置为00,否则后续命令中会报错(比如报数据库更新错误,此时依然会产生证书,但是c++代码加载证书时却会报错)

打开openssl.cnf文件,可以看到其中的一些目录结构要求

cmd进入openssl.exe所在目录下,依次输入以下命令(证书名字可以自己调整,输入过程中需要输入一些信息,如国家,省,市,主机名,邮件,密码等,请尽量保持一致) 例如我的主机名就写127.0.0.1 可以检验证书域名,代码在客户端给出

产生CA自签名证书
openssl.exe genrsa -out private\ca.key -rand private.rnd -des 2048
openssl.exe req -new -x509 -days 3650 -key private\ca.key -out private\ca.crt -config openssl.cnf
openssl.exe x509 -in private\ca.crt -noout -text

产生server的证书过程
openssl.exe genrsa -out private\server.key 1024
openssl.exe req -new -key private\server.key -out newcerts\server.csr -config openssl.cnf
openssl.exe ca -in newcerts\server.csr -cert private\ca.crt -keyfile private\ca.key
-config openssl.cnf -policy policy_anything -out certs\server.crt
openssl.exe x509 -in certs\server.crt -noout -text

产生proxy的证书过程
openssl.exe genrsa -out private\proxy.key 1024
openssl.exe req -new -key private\proxy.key -out newcerts\proxy.csr -config openssl.cnf
openssl.exe ca -in newcerts\proxy.csr -cert private\ca.crt -keyfile private\ca.key -config openssl.cnf -policy policy_anything -out certs\proxy.crt
openssl.exe x509 -in certs\proxy.crt -noout -text

产生client的证书过程
openssl.exe genrsa -out private\client.key 1024
openssl.exe req -new -key private\client.key -out newcerts\client.csr -config openssl.cnf
openssl.exe ca -in newcerts\client.csr -cert private\ca.crt -keyfile private\ca.key -config openssl.cnf -policy policy_anything -out certs\client.crt
openssl.exe x509 -in certs\client.crt -noout -text

ca.crt为自签名证书;
server.crt,server.key为服务器端的证书和私钥文件;
proxy.crt,proxy.key为代理服务器端的证书和私钥文件;
client.crt,client.key为客户端的证书和私钥文件。

系统内置证书问题

现在有个问题,当访问百度,支付宝,银联的时候,浏览器是内置证书,怎么获取批量获取这些证书呢?
在cmd中输入certmgr.msc

选择受信任的根证书颁发机构,全选,点邮件,所有任务,导出
技术分享
输入密码

就生成一个pfx文件,现在只要用openssl转成cer文件就可以了,命令
openssl pkcs12 -nodes -nokeys -in 11.pfx -out 1.cer -passin pass:123456
在程序中使用SSL_CTX_load_verify_locations 预先加载这个1.cer文件就可以了

Android BKS证书

Android加载bks格式证书,Ios/Pc加载cer格式证书,一般而言,生成cer格式比较常见,因此需要进行cer转bks操作,操作步骤如下:

首先要下载特定版本的JCE Provider包
http://www.bouncycastle.org/download/bcprov-jdk15on-146.jar
或者
http://pan.baidu.com/s/1c1ur13y

转换命令说明:
keytool -importcert -v -trustcacerts -alias 位置1 \
-file 位置2 \
-keystore 位置3 -storetype BKS \
-providerclass org.bouncycastle.jce.provider.BouncyCastleProvider \
-providerpath 位置4 -storepass 位置5

位置1:是个随便取的别名
位置2:cer或crt证书的全地址
位置3:生成后bks文件的位置,建议写全地址
位置4:上面下载JCE Provider包的位置
位置5:生成后证书的密码

转换完整示例
keytool -importcert -v -trustcacerts -alias my12306 -file C:\Users\Administrator\Desktop\证书\srca.cer -keystore C:\Users\Administrator\Desktop\证书\srca.bks -storetype BKS -providerclass org.bouncycastle.jce.provider.BouncyCastleProvider -providerpath C:\Users\Administrator\Desktop\证书\bcprov-jdk15on-146.jar -storepass 123456
