https 443 rsa 非对称128加密 安全类交易可以使用rsa 1024位加密算法
https是ssl(secure socket layer)的一种
单向 客户端单向访问服务器(安全)
根证书 rootCA
服务器认证 serverCA




双向认证
根证书
生成一对不对称密钥，公钥public key(加密) 和私钥 private key(解密),一个私钥对应多个公钥
用密钥产生请求，同时交给root机构
root机构进行签名
服务器认证
客户端认证

过程：客户端请求认证，取得证书，每次访问携带证书


md5 和sha指纹加密算法




使用openssl来签证书
1 下载安装文件
http://slproweb.com/products/Win32OpenSSL.html


2 安装完成后，设置环境变量


OPENSSL_CONF
D:\tools\OpenSSL-Win32\bin\openssl.cfg
path
D:\tools\OpenSSL-Win32\bin
3 生成根证书所用密钥
openssl genrsa -des3 -out ca.key 1024
示例
D:\tools\opensslca>openssl genrsa -des3 -out ca.key 1024
Loading 'screen' into random state - done
Generating RSA private key, 1024 bit long modulus
........++++++
.....................................................................++++++
e is 65537 (0x10001)
Enter pass phrase for ca.key: 输入密码
Verifying - Enter pass phrase for ca.key: 再次输入密码




去除ca密钥的口令
openssl rsa -in ca.key -out ca.key


D:\tools\opensslca>openssl rsa -in ca.key -out ca.key
Enter pass phrase for ca.key:
writing RSA key


生成rootCA
openssl req -new -x509 -key ca.key -out ca.crt -config D:\tools\OpenSSL-Win32\bin\openssl.cfg


国家:CN
省：SH
市：SH
公司名：yue
主机名：Nemo-20100613CG



D:\tools\opensslca>openssl req -new -x509 -key ca.key -out ca.crt -config D:\too
ls\OpenSSL-Win32\bin\openssl.cfg
Loading 'screen' into random state - done
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]:SH
Locality Name (eg, city) []:SH
Organization Name (eg, company) [Internet Widgits Pty Ltd]:yue
Organizational Unit Name (eg, section) []:Nemo-20100613CG
Common Name (e.g. server FQDN or YOUR name) []:Nemo-20100613CG
Email Address []:[email protected]



同时会在C:\WINDOWS\system32\drivers\etc\hosts文件中添加如下行：
127.0.0.1 cn.yue.com


将ROOT CA导入客户端的根级信任域,所有客户端都需要导入
internate 选项-->证书-->导入




生成web服务端的证书使用rootca签名aaaaaa
命令如下：
openssl genrsa -des3 -out server.key 1024




去除密码
openssl rsa -in server.key -out server.key


生成服务端证书签名:
openssl req -new -key server.key -out server.csr


使用rootCA 请求web服务器的证书,进行签名认证
openssl ca -in server.csr -out server.crt -cert ca.crt -keyfile ca.key

出现如下错误：
D:\tools\opensslca>openssl ca -in server.csr -out server.crt -cert ca.crt -keyfi
le ca.key
Using configuration from D:\tools\OpenSSL-Win32\bin\openssl.cfg
Loading 'screen' into random state - done
I am unable to access the ./demoCA/newcerts directory
./demoCA/newcerts: No such file or directory


解决方法:
md demoCA
cd demoCA
md newcerts
cd ..
@echo>index.txt
@echo>serial
@echo 01 >serial


重新生成Web服务器的server.crt证书：
openssl ca -in server.csr -out server.crt -cert ca.crt -keyfile ca.key


结果如下：


Using configuration from D:\tools\OpenSSL-Win32\bin\openssl.cfg
Loading 'screen' into random state - done
Check that the request matches the signature
Signature ok
